+Subject: polygon-reduce: Reduce broken stopped-edge continuation
+
+This is hopefully a lesser used path and the attempted optimisation to
+continue a stopped edge with a colinear stopped edge highly unlikely and
+lost in the noise of the general inefficiency of the routine. As it was
+broken, rather than attempt to rectify the "optimisation" remove it.

+
+There is need to loop over number of glyphs to check wether the glyph
+image is a ARGB32 as the font's antialias option can be used for checking.
+If antialias is SUBPIXEL or BEST, the glyph surface will be ARGB32,
+otherwise it will be A8 format. Therefore we will only be using
+component-alpha at SUBPIXEL (or better) font quality and only then need
+a mask for multiple pass glyph composition.

+Subject: composite-rectangles: Trim extents for SOURCE and CLEAR to the mask
+
+The SOURCE and CLEAR are the odd pair in Cairo's range of operators that
+are bound by the shape/mask, but are unbound by the source. This
+regularly leads to bugs as only track the bound/unbound rectangles and
+confuse the meaning when bound only by the mask.
+
+What is required is that the unbound extents in this case is only
+trimmed by the mask (the bounded extents are still the intersection of
+all).

+
+We need to fix y-axis origin when map a GL surface to image surface for
+non-texture GL surface.
+
+Test cases: extended-blend-alpha-mask, extended-blend-mask.
+Although the image outputs is not right, but the image on the first grid
+(upper-left corner) is correct comparing to image output.

+Subject: xlib: Disable fallback compositor with xlib-xcb
+
+When xlib-xcb is enabled, this is just dead code which is never used. Thus, this
+shouldn't hurt. However, this does include cairo-xlib-private.h. Shouldn't be a
+problem? Well, that header contains static inline functions which some compiler
+on Solaris will emit even when they are unused.
+
+This brings us to the real problem: That static inline function refers to a
+function which isn't compiled with xlib-xcb and thus linking fails with
+undefined symbols.
+
+This can be reproduced with GCC by adding a call to
+_cairo_xlib_screen_put_gc(NULL, NULL, 0, 0); to
+_cairo_xlib_fallback_compositor_get.
