-====== IsOpenGL ======
-''bool IsOpenGL()''
-{{tag>info needs_examples}}
-===== Description =====
-Returns true if the OpenGL renderer is being used by the client, false if software.
-When used serverside, this function always returns true and emits a [[ProgramError]].
-It works by checking the following conditions:
-  - The mod is being played in a GZDoom-based port (see [[IsGZDoom]]).
-  - ''vid_renderer'' is true.
-  - ''gl_nogl'' is false.
-Only if all three checks pass, the function returns true.
-<note important>
-This function will return an incorrect value if ''vid_renderer'' or ''gl_nogl'' is changed mid-game because the renderer only actually switches after restart, but the values of the cvars change instantly.
