* Clicking on the title with button 1 did not bring the window to the
front. Clicking on the content did - corrected (Terry Blunt)
* Resize did not work for Buttons 2 & 3 - corrected (Terry Blunt)
* Pointer did not change to resize (or move) when passing over window
sides or bottom in "Drag Resize" mode, but in "Drag Move" mode instead.
Fixed. (reported by Bungee and Tony Houghton)
* don't remove shading property from allowed actions when shading,
as the button for unshading gets removed from the titlebar.
