Lior Halphon d146b3a309 Why do I end up writing these 2025-04-03 23:52:04 +03:00
Lior Halphon 42be4ef827 Add flat CRT shader 2024-09-15 20:49:49 +03:00
Lior Halphon 302eaf6eca Migrate changes from the App Store version 2024-05-25 18:15:14 +03:00
Maximilian Mader 00dce71eab
Make shaders compatible with GLES 3.0 
GLES, at least as used in WebGL 2, does not like mixing integers and floats,
for example:
> ERROR: 1:8: '*' : wrong operand types - no operation '*' exists that takes a left-hand operand of type 'mediump 2-component vector of float' and a right operand of type 'const int' (or there is no acceptable conversion)

This patch converts those integer constants into floats.
With this patch the shaders (apart from the master shader) can be used in WebGL contexts too.

LMLB c365c450a7 Fix shaders that break with specific pixel factors 
OmniScaleLegacy seems to has problems with every odd factor (3x, 5x, 7x,
9x, etc.).
SmoothBilinear has problems with 5x and 11x and probably more.

LMLB 0c80ac3296 Fix shaders that sample at texel edges 
Sampling at the edge between texels causes one or the other to be chosen
semi-randomly, depending on rounding errors. Add half a pixel so they
sample at texel centers instead.
