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.
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>.
Eliminate needless (and, it turns out, dangerous) call to ChangeGC on
DestroyGCPrivate.
in cwSetWindowPixmap, check if the pixmap is the screen pixmap and disable
the wrapper by setting the private to NULL.
Wrap InstallColormap so that the DDX doesn't see colormaps from our ARGB
visual (avoids lovely green tint to screen). Also, set visual->nplanes
of ARGB visual to all used (including alpha) planes so DIX can set
pixel values correctly.
Translate automatic update regions correctly to account for borders
When nplanes == 32 (ARGB visuals), mask in all ones for alpha values to
allocated pixel values.
Remove redundant fbAddTraps declaration
Fix fbCopyWindow to work on non-screen pixmaps (not needed yet)
Replace broken clipping code with that from modular tree.
Respect subWindowMode.
has several issues, including:
- CopyWindow and PaintWindow wrappers missing (will be done soon)
- Some segfaults seen in the Render wrappers.
- Xprt server build breaks with Composite.
- DDXs must be recompiled for Composite due to VisualRec size change.
- Composite bugs pointed out by Deron Johnson in email.
Also, reorder XFixes initialization according to comments by Keith which
are also in xserver CVS.
