GL: Fixed a bug where the depth buffer is not written to (#793)

Browse Source 
`glDisable(GL_DEPTH_TEST)` disables not just depth testing but depth writing too. In the OpenGL renderer, it is called even when depth writing is enabled. This commit makes it fall back to `glEnable(GL_DEPTH_TEST)` and `glDepthFunc(GL_ALWAYS)` when it is enabled.
