clayjohn eb07056e70 Add texture reading code to OpenGL3 renderer for web and mobile 
This allows using texture_2d_get on all platforms which is needed for the get_image function

This commit also fixes some OpenGL warnings on the Web platform that came from attempting to map a buffer with zero length
