The rotation state is stored in the xf86_config structure which is not
re-initialized at server reset time. Clean it up at CloseScreen time.
(cherry picked from commit f8db7665dc)
Rotation block handler was re-registering the rotation damage structure,
creating an infinite loop in the damage code. Track registration of the
damage structure to avoid this.
(cherry picked from commit b14f003b0e)
Box transformation from source to dest area was broken, leaving the wrong
areas painted when the crtc origin was non-zero.
When rotating from left to right, the pixmap doesn't get reallocated, and so
no damage was left in the pixmap from xf86RotatePrepare. Separately damage
the whole crtc area when this occurs to repaint the area.
(cherry picked from commit 2a50ca2160)
Add monitor "Rotate" option taking one of "normal", "left", "inverted" or
"right". However, because initial mode selection is made before the screen
is completely initialized, we cannot create the shadow pixmap object at this
point. Pend the shadow pixmap creation until the block handler.
Note that this code is not completely functional yet.
This code comes from the intel driver, so there's no history in this tree.
As the crtc/output-based mode selection code uses ddc, the ddc and i2c
modules have been merged into the server. Attempts to load them are safely
ignored now.
