The call to cnp_drag_restart_dragbox() needs the window member of current_drag_op set up, but was being used before it's set.
Since the struct is memset to 0 before use, don't bother with the static initialiser.

Version 2.37. Tagged as 'Paint-2_37'

Starting with USBDriver 1.30, the scrollwheel is now handled in a
sensible manner, so there's no longer any need to ignore four out of
every five wheel events.

Version 2.36. Tagged as 'Paint-2_36'

As documented in PRM5A, RISC OS 3.5 doesn't support new-format sprites
which have masks. Update the sprite info dialogue "compatibility" field
to reflect this, reporting that the sprite is compatible with RISC OS
3.6 instead.

Messages/Templates: Extra interactive help, new menu templates, new choices dialogue.
PaintChoice.c/h: New source file to handle the choices dialogue, also added to Makefile.

Main.c/h: Transfer ownership of initial_options to PaintChoice.c. Delete setting & parsing of Paint$Options. Export - and constify - Matches() for use elsewhere. Define MAXZOOMFACTOR and replace 999's elsewhere.
Menus.c: Remove advanced options menu, these are now in choices.
MenuD.h: Defines for the iconbar menu, remove advanced options menu.

Version 2.35. Tagged as 'Paint-2_35'

Detail:
  * Fix for 2 colours being editing when the palette is in artist friendly view
  * Disabled 'Rearrange user palette' option by default to keep confusion to a minimum
  * Remove ^P shortcut for 'Edit palette' which could cause a submenu error in some situations

Version 2.33. Tagged as 'Paint-2_33'

Detail:
  Longstanding bug where use of the camera or scissor tool in Export mode with 'new' 1bpp mask sprites didn't work. Change to use SpriteExtend's scaled mask op.

Send Wimp message to correct destination icon rather than the iconbar window.

Version 2.32. Tagged as 'Paint-2_32'

A check (marked DF-300) rejected any attempt to load a palette into a new (ie. RISC OS 3.50+) style sprite. This is bogus because bbc_modevar() is perfectly happy to process a sprite mode word and return Log2bpp, which is all that was required. Confirmed on RISC OS 3.50 with
  SYS"OS_ReadModeVariable",&202D0169,9 TO,,log2bpp
which gives 3 for a 256 colour 180dpi sprite.
Ref: https://www.riscosopen.org//forum/forums/4/topics/14966

Second, a logic error introduced in Paint-2_26 meant that loading from a file any 256 entry palette (old or new sprite) would result in the palette being reset to the kernel default. This is because there are 2 callers of menus_set_palette() with non-NULL palette pointers, but only 1 wants a default palette. Signal this case by passing -256 entries.

Version 2.31. Tagged as 'Paint-2_31'

Detail:
  Move the menu entry tokens out of the !Help messages section so they don't get tokenised.

Version 2.30. Not tagged

Detail:
  Previously a small (eg. 100x100) sprite being
  * zoomed in until it fills the screen
  * zoom 1:1
  * zoom in again
  would lead to a large black border in width as the sprite grew, but not in height. Now ensures the width is clamped to the minimum sprite width.

Version 2.30. Tagged as 'Paint-2_30'

Detail:
  The colour panel swatch was being redrawn unnecessarily on every open window request due to not knowing whether the furniture icons had changed size. Now, only recalculate the sizes and force a redraw on a mode change event, this eliminates the flicker when moving the sprite window around.

Detail:
  Now that there a popup menus on the create sprite window, it can't be used as a menu dialogue (because the Wimp only allows one window) from a submenu arrow. Change the menu entry to add an ellipsis and open it as a plain dialogue window.

Detail:
  In the create sprite dialogue the menus for colour/palette didn't open in the right place. Compute the offset as the Style Guide recommends.

Detail:
  Promoted the colour panel variables used to store dimensions based off the window furniture sizes to use ints instead of chars as they could, at least theoretically, exceed 255 OS units on a custom desktop.
Admin:

Detail:
  * If the source sprite has an old-style bit mask, solid pixels in the exported sprite's mask may have a different value to the source sprite's. For example 0xFF -> 0xFC.
  * The OS seems to render such intermediate mask values inconsistently.
  Applicable GCOL commands have now replaced with OS_SetColour calls (taken from another fix elsewhere in the code that dates back to Acorn).

Version 2.29. Tagged as 'Paint-2_29'

Detail:
  Remapping would never occur if the confirmation box was disabled.
Admin:
  Submission for the Paint bounty.

Version 2.28. Not tagged

Detail:
  * Menus rearranged so "Advanced" is renamed "Palette options"; "Extra click for input focus" moved to the Paint menu.
  * The "Highlight background colour" menu option has been removed to simplify the interface.
  * To address all the differences of opinion around the artist-friendly palette arrangement, the default behaviour is to not show the confirmation dialogue box plus a further menu option "Rearrange user palettes" (ticked by default).
    If the latter's unticked, the remapping to artist-friendly (upon Edit palette) will never take place; if it's ticked, the remapping will always take place except when the confirmation box is enabled and the user clicks Default.
  * Greyed out palette options when there's not a full/default 256-colour palette, as appropriate.
  * Help text updated to reflect these changes.

Version 2.28. Tagged as 'Paint-2_28'

Detail:
  * Sprite editor windows gain input focus on first click (there's an option to disable this behaviour too)
  * Zoom with Ctrl+resize window (in addition to Ctrl+Scrollwheel already implemented)
  * Key shortcuts in Sprite editor windows

Version 2.27. Tagged as 'Paint-2_27'

Detail:
  * Artist friendly colour ordering of 256 colour palette, and option to reorder pixel data for the remapped palette
  * Full 256 colour sprites can be created (as well as 64/16 entry VIDC compatible ones)
  * Colour indicator swatch in the bottom left corner of the sprite window
  * Adjust click on colours to paint with background colour
  * Shift-select as a shortcut to Paint > Select colour
  * Shift-adjust ditto for background colour

Version 2.26. Tagged as 'Paint-2_26'

Long standing disable of idle events when they are needed. Steps to recreate:
* Create a sprite with a palette
* Paint a little with any brush tool
* Go to Paint > Edit palette to open the colour picker (ensuring that the menu tree, the mouse, and the colour picker are within the bounds of the sprite view being painted)
* Collapse the menu tree and carry on painting with the brush tool
The brush tool now only produces output on click, not drag. This is because the idle events are no longer enabled, they were lost in merely opening the picker.

"oh god a sprite window's gone walkies" observed in trace during development.
Triggered when sprwindow_delete() is called when there's only one sprite window and you close it. This is because of an earlier change which commented out
  beforeus = /*(main_sprite_window *) &*/us->sprite->windows;
The additional addressof operation would have introduced one extra iteration to the loop that followed (with the beforeus->link variable at offset 0, it would just dereference the pointer on the first iteration). Now the case of beforeus == us is explicitly checked.

Version 2.25. Tagged as 'Paint-2_25'

Detail:
  * Sprite filer window can now gain input focus
  * Change sprite/selection menu to add clipboard operations
  * Change 'Copy' to 'Copy as' to keep original copy with rename option
  * Add clipboard copy/paste/cut functionality
  * Add key bindings for clipboard bits
  * Remove existing drag of selection and replace with drag and drop protocol data export
  * Add drag and drop data import

Version 2.24. Tagged as 'Paint-2_24'

PSprite.c: move the trace message up before the label, so if tb is NULL there isn't a NULL pointer dereference
guard.c: refactor assert() to not check ptr!=0 a second time
Found by cppcheck static analysis.
Tagged as Paint-2_23-1 since both are debug code only.

Detail:
  The mouse wheel can now be used to
  * scroll up/down
  * +shift to scroll left/right
  * +control to zoom in/out
  on an open sprite editing window.
  The sprite editing window will auto scroll when the mouse approaches the border with
  * the move whole sprite "hand" tool
  * the copy block "camera" tool
  * the move block "scissors" tool

Version 2.23. Tagged as 'Paint-2_23'

Detail:
  Put in minimal support to create 4k and 64k sprites (currently, TBGR only) so that the User Guide chapter makes sense.
  Previously it was only possible to create such sprites by switching to that mode and doing a screen capture.
Admin:
  Tested on RISC OS 4.02 (ie. without 4k & 64k support) and RISC OS 5.23 (ie. with).

Version 2.22. Tagged as 'Paint-2_22'

Detail:
  The spray tool rate was ultimately determined by the number of wimp polls per second, which on a fast CPU can be 10,000's making the spray can more of a circle drawing tool.
  Use OS_ReadMonotonicTime to moderate the spray rate, so the speed of the CPU doesn't matter.
  Default density increased to 100 to achieve roughly the same density as a StrongARM Risc PC would previously.

  Submission for the Paint bounty.
  Built, but no run time testing.

Detail:
  c/Menus - Fix sprite sort code to take into account the fact that variable-length array allocations may cause flex blocks to be moved (due to CLib allocating the array from the heap)
Admin:
  Tested on Raspberry Pi
  Appears to fix 'sort by name' sometimes resulting in a random sort order being used
  Will hopefully fix 'out of memory' error reported on forums (unable to reproduce here, but this is a likely cause)

  Fixes issue reported on forums with 'Not enough memory' errors from SpriteExtend when resizing or adding rows/columns to alpha-masked sprites: https://www.riscosopen.org/forum/forums/4/topics/3610


Version 2.19. Tagged as 'Paint-2_19'

The 'shapshot' window shouldn't have a close icon, otherwise it automatically gets an iconise icon, and you can't sensibly iconise or uniconise it as it's transitory.

Version 2.18. Tagged as 'Paint-2_18'

Message_SetPrinter renamed.

Version 2.17. Tagged as 'Paint-2_17'

Detail:
  - Handling of currently selected foreground & background colour rewritten; colour is now stored as a 'main_colour' struct, in order to allow representation of alpha level, pixel colour/palette index (which must be 4 bytes for things like CMYK) and ECF index (previously encoded as negative colour values). Fixes crashes when editing RISC OS 5 32bpp ARGB sprites. Note that although the alpha level is now stored internally, and tools should mostly respect it, palette/colour picker limitations mean that only 0/255 is available when selecting colours.
  - "Select colour" code rewritten to decode all the new pixel formats correctly; colours_entry() now accepts a sprite mode word instead of a number-of-colours value
  - "Full info" display tweaked to give more information about the mask (now displays no mask, normal mask, alpha mask, alpha channel)
  - Sprite info dialog extended to display lots more information, including OS version compatibility
  - Fix sprite menu to disallow add/remove mask option if the sprite has a RISC OS 5 alpha channel
  - Fix ECF pattern that's used for the background of masked sprites to get black/white colour values from ColourTrans when in >8bpp modes, to ensure correct colours in new RISC OS 5 modes
  - Fix palette window to render ECF patterns correctly - when creating the sprite that shows the ECF pattern in the palette, psprite_setup_ecf() was failing to set its palette due to passing a sprite pointer to ColourTrans but setting the flags as if it was a sprite name
  - Fix sprwindow_redisplay() and sprwindow_invalidate() to refresh the display correctly when in full info mode; was previously assuming only one column of sprites visible
  - Fix sprites with alpha channels to have the mask ECF pattern plotted in the background
  Files changed:
  - Resources/UK/Messages, Resources/UK/Templates,fec, c/Colours, c/Main, c/Menus, c/PSprite, c/SprWindow, c/Tools, h/Colours, h/MenuD, h/PSprite, h/main
Admin:

Version 2.16. Tagged as 'Paint-2_16'

Detail:
  c/Main, c/PSprite, h/main - Update window background rendering & sprite translation table caching to work properly with new screen modes.
  c/Main, c/Menus, c/PSprite, h/PSprite, h/main - Code to generate description text for sprite colour count now uses new shared function, psprite_get_colours(), which understands the new sprite formats and won't crash horribly if given something unknown.
Admin:
  Tested on BB-xM with new format sprites and new screen modes
  Needs extending to report more info about new format sprites (RGB order, alpha channel, wide mask, etc.) along with relevant editing facilities.

Version 2.15. Tagged as 'Paint-2_15'

Paint, when renaming a sprite via alt-clicking on the name, would silently do nothing if the target name already exists. This was different behaviour to renaming via the menu (which gives "Sprite name already exists") and the Filer (which gives "Filename already exists". Now, alt-click-rename also gives a suitable error.

Version 2.14. Tagged as 'Paint-2_14'

Uninitialised 'transprite' member now set to NULL.

Version 2.13. Tagged as 'Paint-2_13'

Specifically, in the filer when you menu click on a file it is temporarily selected. Clicking on a different file loses the first temporary selection and moves the highlight to the new file. This behaviour is skipped if there are already files selected (using left or right click).
This change makes !Paint behave this way too, previously the menu click was a permanent selection, so menu clicking elsewhere on a different sprite would actually manipulate the sprite selected some time earlier - very confusing.
Tidy ups
 * Remove hardwired mouse button bitmask operations, now uses defines from <wimp.h>.
 * Use OS_Byte numbers from header

Version 2.12. Tagged as 'Paint-2_12'

Also make use of (some) shared makefiles.

Version 2.11. Tagged as 'Paint-2_11'

Version 0.99 was the generally available version, looking at the change logs 0.80 was an internal QA copy.
