3e12766ced21f82a68008cfaf3114e0dd57c8e2c WebGL: premultipliedAlpha=false is composited incorrectly
not a security fix
confidence 0.08
signal score 8.67
Source/WTF/
Classified as not security-relevant.
Triage note: Adds HAVE(IOSURFACE_ALPHA_CHANNEL_MODE) SPI and an IOSurfaceOptions.alphaPremultiplication path so GraphicsContextGL IOSurfaces carry straight/premultiplied alpha. Feature/SPI wiring, no bug.
