This was an attempt to avoid scratch gc creation and validation for paintwin
because that was expensive. This is not the case in current servers, and the
danger of failure to implement it correctly (as seen in all previous
implementations) is high enough to justify removing it. No performance
difference detected with x11perf -create -move -resize -circulate on Xvfb.
Leave the screen hooks for PaintWindow* in for now to avoid ABI change.
compNewPixmap copies bits from the parent window to the redirected child
pixmap to populate the pixmap with reasonable data. It cannot always use
CopyArea as that only works across matching depths. Use Composite when
the depths do not match.
This patch changes the semantics of manual redirect windows so that they no
longer affect the clip list of their parent. Doing this means the parent can
draw to the area covered by the child without using IncludeInferiors. More
importantly, this also means that the parent receives expose events when
that region is damaged by other actions.
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>.
to me.
Clean up transition between cheap and expensive GC wrappers by using the
prologue and epilogue macros. Before, the GC would be left unvalidated
sometimes which would cause all kinds of entertaining bugs against a
DDX which cares (XAA).
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.
