Workaround freeze on Mac Chrome when checking read pixel config support.
Chromium may ask us to read back from locked IOSurfaces. Calling the command buffer's
glGetIntegerv() with GL_IMPLEMENTATION_COLOR_READ_FORMAT/_TYPE causes the command buffer
to make a call to check the framebuffer status which can hang the driver. So in Mac Chromium
we always use a temporary surface to test for glReadPixels format/type support.
