Description Martin Gerhardy 2012-08-27 02:42:25 UTC 
I've extended the gl error checks.

This is needed because on my system there are errors in the renderer that are hard to find.

Also glError can return multiple errors. Even if SDL_SetError would only contain the last one of course, the SDL log facilities are able to get the output for each error.
Comment 1 Martin Gerhardy 2012-08-27 02:43:09 UTC 
Maybe the GL_CheckError stuff should go into a header that can be shared between the opengl, opengles and opengles2 renderers?

Your patch has been massaged and applied, and it caught an error in the OpenGL viewport code.

Thanks!

It may be worth extending this to the OpenGL ES renderers.  Feel free to reopen this bug and add a patch if you think it's worth it.
