Env projectedtexture

Casting shadows.

Creates a dynamic shadow-casting light that affects all objects in the world. Used for the Episode Two flashlight.

Enabling multiple shadow maps

Valve's games only allow one projected texture to cast shadows at a time - including the player's flashlight! To surmount this, shadow casting can be disabled with the enableshadows KV, or for a proper solution a programmer can perform this fix:

CClientShadowMgr::Init()
	- bool bTools = CommandLine()->CheckParm( "-tools" ) != NULL;
	- m_nMaxDepthTextureShadows = bTools ? 4 : 1;	// Just one shadow depth texture in games, more in tools

	+ m_nMaxDepthTextureShadows = YOUR_CHOSEN_MAX;

Garry's Mod has already had this done. Thanks to Garry for sharing the code!
