Some Android emulator versions fail on rendering because glShaderSource in TextureMapperShaderProgram fails with 0x505 GL_OUT_OF_MEMORY. It turns out that Android emulator OpenGL ES implementation doesn't implicitly define any precision to samplerExternalOES. Adding precision hint to samplerExternalOES across all platforms is harmless because OpenGL ES implementation is not required to use hint information. This is needed for WPEView/Android.
