[client] egl: add linear downscale filter shader 2021-08-14 00:42:35 +00:00			`#version 300 es`
[client] egl: switch from `mediump` to `highp` This fixes a rounding issue on certain hardware (NVidia) which actually implement mediump as half precision (16-bit) float. It's safe to assume `highp` is available as if the GPU does not support it, then the shader compiler will try to find a lower precision that is supported by the GPU 2023-03-05 03:10:21 +00:00			`precision highp float;`
