// Workaround for a bug on some Adreno 308 devices with Android 9. The driver reports a GL
// version of 3.0, and a GLSL version of 3.1. If we use version 310 shaders, the driver reports
// that it's not supported. To keep things simple, we pin the GLSL version to the GL version.
// Note that GLSL versions have an extra digit on their minor level, so we have to scale up
// the GL version's minor revision to get a comparable GLSL version. This logic can easily
// create invalid GLSL versions (older GL didn't keep the versions in sync), but the checks
// below will further pin the GLSL generation correctly.
