Geoffrey McRae	91b0cba145	[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 14:10:21 +11:00
Quantum	bb91b41c64	[client] egl: look at 3x3 around the pixel instead of 4x4 ... Using 4x4 means that some pixels will be outside of the lanczos window. The ideal lanczos function should in fact be zero in those areas, so we shouldn't waste time processing those pixels. I can't notice any difference in the results.	2021-08-19 15:52:44 +10:00
