Hash :329f2eb9 Message :Fix crash when GL_LoadFunctions()/GLES2_LoadFunctions() fails
https://bugzilla.libsdl.org/show_bug.cgi?id=4350
We can't safely call GL_DestroyRenderer() until GL_LoadFunctions()
succeeds because we will be missing functions that we try to use
when activating the renderer for destruction if we have an GL context.
