iPhone 6S - iOS 15.0 - unable to retrieve WebGL2 context
https://bugs.webkit.org/show_bug.cgi?id=226975
rdar://78966563
Patch by Kimmo Kinnunen <[email protected]> on 2021-06-28
Reviewed by Kenneth Russell.
Limit the OpenGL ES 3.0 contexts to iOS GPU Family 3, not
4.
The limit was most likely added to guard sample_compare
lod_options properties .lod and .gradient. However, these
are always supported on iOS.
Currently there is already ES 3.0 features implemented
in ANGLE that are guarded by iOS GPU Family 3.
Fixes WebGL 2.0 to work on iPhone6s and similar
devices (A9, A9X).
