Subject: [PATCH 3/3] Add support for BGRA glyphs display and scaling
Display is done using an XRender Picture, as XRender
glyphs are incompatible with BGRA rendering due to
their use of the glyph bitmap as a mask.
Scaling is done by averaging all relevant pixel, which gives
much better result than nearest pixel sampling while staying
simple enough and not too computationally expensive.
This enables color emoji rendering support.
Fixes: #6
