R5/R6 type icons now behave more usefully with button types other than click,
release and auto-repeat.

Prevented coordinate overflow in dragboxes.

Stopped clipped dragboxes from flickering more than non-clipped ones.

Fixed a bug whereby data aborts occurred when generating the translation table
for inverted and/or shaded 256-colour sprites, if the first 256-colour sprite
plotted since the Wimp's cached translation table was invalidated (either by
Service_InvalidateCache or by plotting a 256-colour sprite after a non-256-
colour sprite one) was at an address that had since been invalidated or paged
out. This fixes a long-standing problem with 256-colour sprites in the desktop,
but which only happened sporadically.

Prevented palette corruption in paletted ( <256-colour) modes when the pointer
reverts from an autoscroll pointer to its original setting.

Fixed bug introduced in last build, where clicking on the bottom pixel row of a
horixontal scrollbar, or the left pixel column of a back icon, caused a crash.

All Wimp-drawn solid rectangles are now be plotted much faster - typically
around twice as fast - translating to a typical 30% increase in speed of
plotting filled icons. Improvements will be better still in cases where icons
are drawn in a non-contiguous order: this commonly affects Toolbox applications.

When a dialogue box is opened from a menu, the Wimp will no longer attempt to
place the caret in a shaded or deleted icon, but it will do so for a type-14
(writable/click/drag) icon, as well as the standard type-15 (writable) icons.
This brings it in line with KA-validation up/down arrow actions.
