      Slacken pointer checks · 42e284a3
      Robert Sprowson authored
      The pointer comparison checking required when running in a system with > 64M memory was tightened up from Wimp-4_75 to Wimp-4_76, but to allow the module to target pre RISC OS 5 systems an option to relax those checks is required.
      Each check has been revisited and where appropriate demarked with a "AcceptLoosePointer" macro, which just remaps the pointer into the stricter form and carries on. In the strict checking case, the macro reduces to nothing.
      
      Detail:
      Add AcceptLoosePointers switch.
      Retire singular use of StrongARM switch (calling XOS_SynchroniseCodeAreas is harmless pre StrongARM anyway).
      Rename Ursula_RPC options to RO400.
      Put duplicate documentation in the attic.
      Allow -2 or -1 as the iconbar handle in Wimp_ResizeIcon (ticket #203).
      Tighten up the list terminator check in the DebugMemory switch of Memory.s
      
      Tested on RISC OS 3.10 (emulated), 3.50, 3.60, 3.70, 4.02.

      Build fixes for variants pre RISC OS 5 · fc22d68f
      Robert Sprowson authored
      Minor fixups as part of univeral !Boot work.
      Options no longer ASSERT on International_Help (which is a definition exported by the kernel, rather than a build switch), and instead define a switch which is true for > 3.50.
      Non UTF8 supporting case has simple substitutes for Wimp_TextOp.
      Legacy_DomainId and LegacyIRQsema no longer cause NULL pointer dereference.
      MOVeQ => MOVEQ to placate ObjAsm.
      
      Ursula_RPC version built and used briefly on RISC OS 4.02 host. No other run time testing.
      
      Version 5.22. Tagged as 'Wimp-5_22'

      Merged in RISC OS 4.02 changes (including ROM patches). Also som bugfixes. · 3b1e336c
      Ben Avison authored
      Detail:
        RISC OS 4 changes:
        * Font blending for desktop font (based on NC code, but now configurable)
        * 3-D window/menu/iconbar borders
        * Textured menu backgrounds
        * Loss of rubout box in unfilled text+sprite icons
        * *WimpVisualFlags controls various aspects of cosmetic changes above
        * Iconise button "slot" glyph slightly shorter (but only adopted in the RO400
          Resource directory)
        * Command window has front-window flag set
        * Byte at +39 of the window block has gained two new flag bits:
            bit 2 set => this window must never be given a 3D border
            bit 3 set => this window must always be given a 3D border
            (note that ResEd erroneously created windows with both bits set,
            this case is treated as though both bits were clear)
        * Another two colour specifiers on the end of C validation string command
          for icons controls the foreground and background colours to be used when
          the icon is selected
        * Pointer shape is correctly reprogrammed by the creation of icon
          underneath it
        * Full stops in writable icons are treated the same as spaces from the
          point of view of cursor navigation
        * spritesize routine returns a size of 0 if the sprite didn't exist
          (probably fixes some rendering problems)
        * Adjust-click on back icon brings window to front
        My changes:
        * DeleteRight turned on
        * Icon bar title background is set to default in all resource sets (avoids
          translation table recalc)
        * Error box title now cream across all resource sets
        * RISC OS 4 changes made 32-bit compatible / high addresses safe
        * Undocumented FullIconClipping option disabled
        * Command help made consistent for internationalised and non-
          internationalised builds
        * WimpVisualFlags defaults made sensible
        * Menu side width affected by ThreeD option at *run* time not assemble time
        * Right-clicking on menus with writable items no longer data aborts
        * Auto-opened menus are now at RHS of current icon (matches RISC OS 3.1)
        * Colour menus were knackered unless menu tiling was enabled
        * Fixed a bug whereby adding messages to a task that wanted all messages
          actually caused it to lose all other messages. The RISC OS 4 fix for
          this didn't work
        * Fixed bug introduced in version 4.76: tasks that wanted no messages got
          all of them
        * Autoscrolling is updated every 8 cs rather than every 12 cs
        * Added menu texture to pre-RISC OS 4 sprites files
      Admin:
        Tested on Tungsten.

      UTF-8 support from previous version switched in; additional alphabet-... · 2c759475
      Ben Avison authored
      UTF-8 support from previous version switched in; additional alphabet- conditional support added as follows:
      
      * Correctly converts character index returned from Font_FindCaret into byte
        index into raw string.
      * Left-arrow, right-arrow, delete-left and delete-right now act as far as
        the next character boundary, instead of to the next byte.
      * Menu item text justification works again (it relies on overwriting spaces
        with hard space characters, which are two-byte characters in UTF-8).
      * General key handling code has been rewritten. The Wimp now has three
        internal key input buffers - one each for taking keyboard-generated,
        task-generated, and function-key-generated strings. Each input buffer is
        processed in chunks of one character, rather than one byte; malformed
        UTF-8 characters are rejected, so tasks don't have to worry about them
        (simplifying their character-handling code). There is also a key output
        buffer, to ensure that (UTF-8) sequences of Key_Pressed events are not
        broken up.
      * As a result of the above, multiple calls to Wimp_ProcessKey are now
        possible between calls to Wimp_Poll. Previously, this resulted in bytes
        getting jumbled up - making it useless for input of UTF-8 characters.
      * Multi-byte characters are inserted into writeable icons in one go, so you
        don't see a brief flicker of the "malformed character" symbol while the
        initial bytes are being inserted.
      * Multi-byte characters that don't entirely fit in a writeable icon buffer
        are not inserted at all.
      * A new validation string command ("U") can limit the contents of a
        writeable by number of characters, instead of bytes. This will hide the
        character sizes from the user interface.
      * Allowable characters (validation string command "A") now works on Unicode
        characters and character ranges.
      * Various other minor bugs are fixed (Wimp_ProcessKey 13 can activate a
        writeable menu item, Shift-arrow keys are always consistent in firing off
        Key_Pressed events, etc.)
      * Password icons supported: one symbol is displayed for each character
        (instead of for each byte); the display character (validation string
        command "D") can be any UTF-8 character; correctly displays the caret
        after set-caret-by-index calls, even though characters in the processed
        string are different width to those in the raw string, in password icons.
      
      Other changes:
      * The border around NC-style error boxes is resized when the error window
        is grown or shrunk.
      * Messages, CmdHelp and Template files made consistent across resource
        directories, including support for all Ursula features.
      * ShrinkableAreas turned back on in System=RCA builds.
      * User interface features of desktop OS builds standardised.
