What happened here is that when fixing bug #5734 we cahnged the
glyph image cache lookup to never return a NULL pointer, but to
instead return a 0x0 image surface. We didn't also update code
that was looking for a NULL pointer here, and as such we were
calling XRenderAddGlyphs with a 0x0 image which apparently
tickles a bug in some X servers.
If the BitBlt in get_image fails, we pretty much can't do anything -- so
fill the destination with white and hope for the best. This enables
somewhat accurate printing of complex operations. Also, check the
destination device caps before calling AlphaBlend; return UNSUPPORTED if
the destination DC can't do AlphaBlend.

If the DC is a display DC, inspect its depth and set out local format
appropriately. If it's not a display DC, assume RGB24.

Fixes up src coords and width/height before calling AlphaBlend/BitBlt; it's
an error to try to use a region that extents outside of the source surface
as a source DC.
Doesn't repair the extra region relative to the operator -- e.g. regions
outside of an ARGB source surface with SOURCE operator should be cleared
to fully transparent black in the destination.

Change a little the logic in hinting to follow the same
logic as Xft and doesn't try to mix FT_LOAD_TARGET which should not be
mixed (based on David Turner comments)
Move face-flipping from inside _cairo_stroker_add_caps to new _cairo_stroker_add_leading_cap variant of _cairo_stoker_add_cap.
Change to call _cairo_stroker_add_leading_cap or _cairo_stroker_add_trailing_cap as appropriate.
Remove dash-caps-joins from the XFAIL list and add reference image.
Portability improvements for win32 thanks to Hans Breuer <hans@breuer.org>:
Defined sized-integer types when under the influence of _MSC_VER and without stdint.h.
Use #error which is more portable than #warning, (and more indicative of where we want to be before the next release).
src/cairoint.h : win32 specific definitions for CAIRO_MUTEX_DECLARE, CAIRO_MUTEX_LOCK etc. [not based on win32 mutex but critical sections]
src/cairo-win32-surface.c : add DllMain() to do global, single-threaded 'mutex' (de)initialization. No ifdefs needed, some variables would simply not be used when the respective backend would not be compiled in.
Treat more alpha values as translucent (up to 0.999)
Fix emit_image to actually use a temporary image when necessary.
Change PS coordinate space to match cairo (top-down), adjust PS output to use new space.
Find more cases where PS output was not supported and fall back to image surface.
