Alberto Ruiz a1cef62f43 Add GBM vs image-surface EGL benchmark example ... Add examples/gbm-egl-benchmark.c, a headless benchmark that compares the display-path cost of uploading Cairo-rendered content to a GL texture via two methods: Image surface: glTexSubImage2D (CPU → GPU memcpy) GBM surface: EGL DMA-BUF import (zero-copy) The benchmark renders an animated Cairo scene at the requested resolution, then measures only the upload/import step per frame. It runs entirely on a DRM render node with no window system required. Typical results on AMD Radeon RX 580: 1080p (7.9 MB/frame): ~24x faster with GBM (1.42 ms → 0.06 ms) 4K (31.6 MB/frame): ~80x faster with GBM (5.18 ms → 0.07 ms) Built automatically when gbm, egl, and glesv2 are all available.		2026-03-23 23:05:56 +00:00
