Simon Hausmann	8e8943b8fe	Clean up texture atlas allocation code ... Let each atlas texture know its index, so that it can return the final allocation result right away.	2020-05-21 18:54:46 +02:00
Simon Hausmann	86eaf027d4	Implement glyph runs grouped by texture ... In order to support multiple font sizes, etc. we have to deal with the fact that the glyphs for a string may not end up all in the same atlas texture. Therefore splitting of glyph runs by texture is necessary. This works but could be improved further by sharing the vertex arrays and just re-binding to a different texture and drawing the run's triangles by index.	2020-05-21 15:51:09 +02:00
