* Add support for BGRA glyphs display and scalingMaxime Coste2022-07-094-30/+293
| | | | | | | | | | | | | | | | | 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 Signed-off-by: Maxime Coste <mawww@kakoune.org> Signed-off-by: Thomas E. Dickey <dickey@invisible-island.net>

| | | | | | | | | The linear search used for randomly selecting a glyph to discard is inefficient. This commit provides for a doubly-linked list which could be maintained by the library to quickly discard the least recently used glyph. Signed-off-by: Thomas E. Dickey <dickey@invisible-island.net>
