#ifdef ANDROID
// bug 736123, blacklist WebGL on Adreno because they do not implement
// glTexSubImage2D in a way that is safe to expose to WebGL </euphemism>
// We don't rely on GfxInfo for this blacklisting, because GfxInfo on Android doesn't know
// about GL strings and GL strings are the only way I know to detect Adreno (EGL Vendor only
// says 'Android'), and it is not convenient to have to create a GL context before GfxInfo::Init()
// is first called.
