Windows now keep the same depth when toggle-size tool is clicked with Adjust.
Fixed bug where drags in Eureka caused branch-through-zeros and other
miscellaneous errors.
Fixed a few stray non-X form SWI calls.
Extended applicability/functionality of "MyEntry" debug macro.

Re-opening a menu structure containing a dialogue box (especially one
containing the caret) was causing data aborts under some OSes/builds.

The minimum title bar length is now the same for windows without line borders,
even if the vertical scroll bar is also absent. This prevents cases when the
title bar shrunk so far that a graphics clipping error occurred.

Wimp_DragBox was looking in R0 for its flags, rather than R3, as specified!

If the pointer was to the right of the central zone, vertical autoscrolling
was working too slowly.

On Service_SwitchingOutputToSprite, the Wimp now re-assesses its idea of the
screen limits. This prevents Wimp_PlotIcon plots outside the current screen
bounds from being optimised out.

Autoscroll update period extended to 12cs to reduce flicker.

Added Wimp_ReadSysInfo 17 to return configured drag-and-drop scroll startup
delay (in cs) because the CMOS storage isn't easy to read.

Identified and bracketed changes from 3.9x responsible for 24-bit icon colours.

defaultfontcolours now works correctly again.

Introduced new icon colour code. This holds icon colours in 24 bits internally
throughout, rather than treating 24-bit colour specifiers as a special case.
This results in the following bugfixes/improvements:
 * 3D faces and moat colours, and slabbed-in action button backgrounds, can
   all be specified in 24-bits
 * fading of icons is now consistent across icon types, and utilises the
   colour range of >16 colour modes
 * 3D borders now get faded along with the rest of the icon
 * action buttons can now contain sprites (background is correct, and sprite
   is not inverted)
 * various cases where anti-aliasing didn't blend in to the background
   correctly are now fixed
 * conventional and 24-bit specifiers now behave equivalently to each other -
   the same colour specified either way behaves the same when faded, used as
   an EOR colour etc. (greys are now always dithered in 1-bpp modes, even if
   specified in 24-bit)
 * behaviour is now the same whether the Wimp font is the system font or a
   fancy font (amazingly, this wasn't always the case)
 * except for 3D icons, if the icon background matches the work area
   background, it is unaffected by fading - so for example, group boxes can now
   be faded correctly

Switched out AutoHourglass (Mike was concerned about the speed hit).

Corrected *Help syntax strings for On/Off configuration options.

Dragboxes can now be clipped by and/or fixed to a given window's work area
SWI Wimp_AutoScroll implemented
Ursula icon highlighting scheme redesigned

Bugfixes:
Wimp_Extend 11 now performs the same check on R1 as the main SWI handling code
Message blocks now updated if in a dynamic area
Screenblanker now turned off when error box is displayed
ptr_double now turned off when a drag starts
