-====== Renderer identification ======
-===== Introduction =====
-You can identify whether the software or OpenGL renderer is currently being used by calling ''IsOpenGL''.
-<note warning>
-**Things not to do:**
-  * don't just check ''GetCVar("vid_renderer")'' -- the user may also have ''gl_nogl'' set to true.
-  * don't just check for ''vid_renderer'' and ''gl_nogl'' -- the user may be playing in ZDoom, which doesn't have the OpenGL renderer.
-  * don't just use [[source_port_identification|IsGZDoom]] and assume that if the engine is GZDoom, the user is playing in OpenGL renderer.
-  * don't store the value of ''IsOpenGL'' in a variable -- the renderer can change mid-game.
-  * don't check the renderer serverside -- the server has no renderer.
-</note>
-===== IsOpenGL =====
-''bool IsOpenGL()'' -- returns true if the mod is being played in the OpenGL renederer, false if software renderer.
-<note tip>The renderer can change mid-game. Don't store the result of ''IsOpenGL'' in a variable. Instead, simply call it every time.</note>
