# SDL's Cocoa GL backend unconditionally asks for NSOpenGLPFAAllowOfflineRenderers
# *and* pins NSOpenGLPFAScreenMask to one display. On dual-GPU Macs (e.g. Intel +
# Radeon Pro) no pixel format satisfies both, so every SDL_GL_CreateContext fails
# with "Failed creating OpenGL pixel format" — verified with a standalone probe:
# the same attributes minus this one succeed. Drop it; offline renderers are of
# no use to us anyway. Idempotent, runs at configure time before SDL compiles.
