[Impeller] Shaders have implicit int / float conversions. #122324
Description
for example:
float IPFloatTile(float t, float tile_mode) {
if (tile_mode == kTileModeClamp) {
t = clamp(t, 0.0, 1.0);
} else if (tile_mode == kTileModeRepeat) {
t = fract(t);
} else if (tile_mode == kTileModeMirror) {
float t1 = t - 1;
float t2 = t1 - 2 * floor(t1 * 0.5) - 1;
t = abs(t2);
}
return t;
}We should try to get those showing up as compilation errors.
