The webGL backend uses textures to upload quads to the GPU, since it doesn't have storage buffers. Each quad is stored in 10 texels, and we previously fetched each texel 4 times. Although texel fetches are cached, the extra bookkeeping optimized badly, and lead to bad performance. This change replaces the `read_word` calls with `fetch_texel_instance`, and manually unrolls this loop. This gave the following frame time improvements scrolling through delta web: - desktop, 9950x3d iGPU, 1440p, firefox: ~3.3x faster - mobile, Pixel 10 Pro, firefox: ~23x faster --- Release Notes: - [GPUI] Improved performance of webGL quad upload, around a ~3x frame time reduction in typical cases
