Apparently using std::vector::push_back causes heavy inlining in MSVS. This refactor (no functionality change) reduces the binary size from ~10kb for all the gl::Determine* functions plus the holding function (setTextureExtensionSupport) to about 1.4k. The visible size of my compiled 32-bit Release libGLESv2.dll went from 4648 to 4642 kb. Note that using PoD arrays was sinificantly better than using vectors with initializer lists (size was ~4kb instead vs 1.4kb).
