Composite's automatic redirection is a more general mechanism than the
ad-hoc BS machinery, so it's much prettier to implement the one in terms
of the other. Composite now wraps ChangeWindowAttributes and activates
automatic redirection for windows with backing store requested. The old
backing store infrastructure is completely gutted: ABI-visible structures
retain the function pointers, but they never get called, and all the
open-coded conditionals throughout the DIX layer to implement BS are gone.
Note that this is still not a strictly complete implementation of backing
store, since Composite will throw the bits away on unmap and therefore
WhenMapped and Always hints are equivalent.
Before putting anything on the screen, check if the GC was made for the
ScreenRec we want to render to. If not, toss the GC and create a new one. This
is not the best solution but it does the job for now. Same thing for ARGB
cursors except that it's even uglier.
Also remember the screen the cursor was rendered to and check for the right
screen in the BlockHandler, SourceValidate and a few others. Only remove or
restore the cursor if we are rendering to the same screen, otherwise we get
artefacts that are both funky and really annoying.
Improve memory usage by allocating the sprite's memory only to devices that
actually have a sprite and provide means to remove a device's cursor from the
screen (more hotplugging, yay!).
This commit breaks ScreenRec's ABI.
dix: set coreGrab flag for grabs caused by GrabPointer and button presses.
remove virtual core devices from device list, only real devices are in
the list now.
Auto-pair each keyboard with a real pointer if one is available,
provides multiple keyboards automatically after startup if devices
are configured.
fix GuessFreePointerDevice() to do what it's supposed to do.
mi: fix: call miPointerMove from miPointerWarpCursor.
fix: remove unused id field from miCursorInfoRec
don't update sprite for virtual core pointer.
mi: core pointer was checked twice in miSpriteReportDamage,
miSpriteInstallColormap, miSpriteStoreColors, miSpriteSaveDoomedAreas
and miSpriteRealiseCursor
using damage bug (see comment in file) to avoid artefacts
added id field to miCursorInfoPtr, required to pass through to miDC
core pointer uses mpCursors array as well.
added miDCBufferRec for future use with MPX
TAG: MPX_BEFORE_MIDC_API_BREAK
added miCursorInfoRec to contain info of the MPX cursors.
calling miUpdatePointerSprite() from event queue for MPX devices.
adding device-specific processing to miPointer*() functions.
dix: Call to SetCursorPosition in CheckMotion() temporarily disabled.
xfree86/common: call to miPointerUpdateSprite() disabled, is done from the EQ
NOTE: This build will not display cursor images.
BUG: The second mouse does to take correct x coordinates.
Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings.
Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all
source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
Replace miSprite implementation with Damage-based one. Otherwise damage and
misprite conflict causing looping.
Change pScreen usage around a bit to eliminate warnings
