Description
I had a pretty specific issue where emulators that have to translate arm86 > opengl for android were reading miniquads sample_count=1 as requesting MSAA and crashing.
I've bypassed this for now by writing a simple "sample_count:0," in main.rs but it's not the cleanest solution.
Apparantly some devices read miniquads sample_count=1 as direct request for MSAA=1

Research direction
Start from the sample_count workaround described in main.rs and trace how that value reaches the Android/OpenGL path. Compare sample_count values on an affected ARM Android emulator; done means sample_count=1 no longer incorrectly requests MSAA or causes a crash.
