From 7808631e7a9a605d5fe7a1077129c658d9ec47fc Mon Sep 17 00:00:00 2001
From: Maxime Coste <mawww@kakoune.org>
Date: Tue, 22 Oct 2019 22:46:49 +1100
Subject: [PATCH] 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
