The instanced API allows a lot of work to be offloaded to the GPU and makes software rasterization tolerable performance-wise in most cases. This is similar to sd_ass but there are some substantial differences: - It uses a BGRA atlas to allow drawing bitmap emoji. - De-duplicates images internally to significantly reduce atlas size by reusing the same atlas image for different instances. - Exploits bilinear interpolation to further reduce atlas size of some primitives. For example this allows reducing background boxes to one very stretched pixel. Bumps subrandr requirement to `v1.1` since this API is not present in earlier versions.
