For the former we try to use glLogicOp, which works for draw calls but not for texture image calls, and doesn't exist in GLES. For the latter we basically just punt if the planemask isn't trivial. We could probably accelerate both of the above if the GL(SL) below us has something like [[MESA_shader_integer_functions|https://www.opengl.org/registry/specs/MESA/shader_integer_functions.txt]] or [[EXT_framebuffer_fetch|https://www.khronos.org/registry/gles/extensions/EXT/EXT_shader_framebuffer_fetch.txt]]. |
