-====== Port detection ======
-ACSUtils provide a function to detect which engine (source port) it's running on:
-''int IdentifySourcePort()''
-Returns one of the following:
-  * ''PORT_ZDOOM''
-  * ''PORT_GZDOOM''
-  * ''PORT_ZANDRONUM''
-The following functions are provided for easier use:
-  * ''bool IsGZDoom()'' -- returns true if the mod is running on an engine with GZDoom features (this includes GZDoom and Zandronum).
-  * ''bool IsZandronum()'' -- returns true if the mod is running on Zandronum.
-You can also display the name of the port the mod is running in using ''str GetPortName()'':
-<code>
-print(s:"This mod is running in ", s:GetPortName());
-</code>
-It returns one of the following: "ZDoom", "GZDoom", "Zandronum".
-===== Renderer detection =====
-ACSUtils also provides a function to check if Software or OpenGL renderer is used:
-''bool IsOpenGL()''
-It can only be used clientside. It has several features over checking ''vid_renderer'':
-  * It will return false in ZDoom even if ''vid_renderer'' is 1, because ZDoom doesn't have an OpenGL renderer. This can happen if a GZDoom config is used in ZDoom.
-  * It takes ''gl_nogl'' into account, which can disable the OpenGL renderer even if ''vid_renderer'' is 1.
-===== How port detection works =====
-First, ''GetPlayerAccountName(0)'' is called. In Zandronum it returns a string (possibly empty string). In other ports it returns 0, because it's an unknown function.
-Second, existence of ''DynamicLight'' actor is checked by spawning and instantly destroying it. This actor is not present in ZDoom. If it spawns successfully, the port is GZDoom.
-If both checks fail, the port is ZDoom.
