Faded text-plus-sprite icons in Impression and ArtWorks were being plotted incorrectly, due to what appears to have been a workaround for a RISC OS 2

Wimp bug.

A redraw problem turned out to be due to the rectangle limit, so this has been
doubled again.

A number of window-toggling bugs are fixed:
* if a window had no title bar, shift-toggle left a gap before the top of the
  screen
* window status flag bit 19 was always cleared during a call to Wimp_SetExtent
* tasks which called Wimp_SetExtent after an Open_Window_Request (eg the Filer)
  weren't always being considered "full-size" after a shift-toggle operation
* when a non-toggled window and its shift-toggled version were the same size,
  various problems arose (window status flags being wrongly set, toggle button
  being non-responsive for next click, toggle button not being redrawn
  correctly)
