Since glyphs are stored in pixmaps now, they can make their way into VRAM,
which invalidates a bunch of fast-path assumptions in the XAA code. Thus
you end up doing color-expands or WriteBitmap from la-la land and your
aliased glyphs go all funny.
Since XAA isn't ever growing the ability to do sane glyph accel, just force
glyph pixmaps into host memory by catching them at CreatePixmap time.
We need a manual call to SetCursor when we switch from SW to HW rendering and
the other way round. This way we display the new cursor after removing the old
one.
In addition, we only update the internal state for the VCP's sprite. This way,
when we switch back to HW rendering the state is up-to-date and wasn't
overwritten with the other sprite's state.
The second part is a hack. It would be better to keep a state for each sprite,
but then again we don't have hardware that can render multiple cursors so we
might as well do with the hack.
Switches back to HW cursors when sprites other than the VCP are removed.
The current state requires the cursor to change shape once before it updates
to SW / HW rendering (whatever is appropriate), e.g. by moving into a
different window. Until this is done, the cursor is invisible.
The composite overlay window code had several misunderstandings of the
workings of the X server, in particular error handling paths would often
double-free objects. Clean all of this up by using resource destruction as
the sole mechanism for freeing resource-based objects.
Thanks to Owen Taylor for root-causing this one.
If a TreatAsTransparent window has any area in the borderClip, that will be
added to the totalClip region for use by other windows. That's wrong.
Instead, simply empty the borderClip for TreatAsTransparent windows right up
front.
This patch only creates a Files section if required, so if no entries are
added, an empty Files section will not be created.

XQuartz was crashing because the Appkit thread was trying to GetXXXEvents while the Xserver thread was exiting.
This adds some more sanity checks and avoids that crash

When a new device is added, calculate the event size needed if a DCCE event is
sent and set the EQ's event size to this minimum. This avoids reallocs when a
event is sent (which may happen during a SIGIO).
more conservatively (to match Linux's Wacom driver) and
we now receive all tablet-related events.

LeaveVT/EnterVT cycles will free/realloc shadow frame buffers. Because of
this, the presense/absence of that data is insufficient to know whether
the screen function wrappers are necessary. Instead, the 'transform_in_use'
flag should be used.
This patch also adds 'xf86RotateFreeShadow' for drivers to use at LeaveVT
time to free the rotation data; it will be reallocated on EnterVT.
After UpdateDeviceState, the device has the current position in absolute
coordinates, the event has the correct valuator data to be delivered to the
client.
When possible, use UploadToScreen() rather than CompositePicture()
to upload glyphs onto the glyph cache pixmap. This avoids allocating
offscreen memory for each glyph making management of offscreen
areas much more efficient.
