+Subject: gl: use font's antialias option to check whether it needs mask
+
+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).
