The only functional changes in this patch are a removal of use of
Xtrans internals -- replaced by xcb, which doesn't seem to be used
elsewhere in the server? Pity.
Also, a fix to make all X11 windows pop to the front of the display
when the X11.app icon is clicked -- currently takes two clicks,
not sure why.
At least on my system (10.5 with the latest and greatest modules),
Xquartz now builds out of the box. It doesn't quite work yet, but
hey -- you have to start somewhere. ;)
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.
This cleans up server Makefile.ams a little bit, but also means that people
messing with configure.ac need to be careful with whether they put libraries
in the _LIBS or _SYS_LIBS targets. Hopefully the comment in configure.ac will
clarify the issues.
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.
Now, fbcmap_mi.c contains the fb functions which just wrap mi functions.
Previously, these were in fbcmap.c and compiled when XFree86Server was defined.
Now, clients of fbcmap should either use fbcmap.c or fbcmap_mi.c and not worry
about setting the XFree86Server symbol.
