Unified Diff: Source/core/html/canvas/WebGLFramebuffer.cpp

Issue 1120953002: WebGL 2: add read/write framebuffer binding points to related APIs (Closed) Base URL: https://chromium.googlesource.com/chromium/blink.git@master
Patch Set: in DrawingBuffer::commit, we should bind to the single-sampled FB at the end, instead of the multis… Created 5 years, 6 months ago
