Summary: current transformation independent of display

Initial Comment:
[AD] 17/02 Elias writes:

"This reveals another serious problem - the current transformation is
per-display. So it's impossible right now to change the transformation
when you draw into a memory bitmap but never create a display."

This is currently causing programs that don't open a display to crash when doing graphics operations on memory bitmaps.

Message:
Should be fixed with revision 13027 - now both transformation and blending
mode are in the display which makes more sense, but at the same time if no
display is active a per-thread fake display is used instead.
