//
//	DESCRIPTION:	Makes it easy to switch between two resolutions of a material.
//			Just have two versions of all necessary textures available in the
//			appropriate folders ('../sourceimages/lores/' and '../sourceimages/hires/').
//			If the folders don't exist they will be created automatically.
//			If the textures are not explicitly hires or lores textures and still reside
//			in the "sourceimages" directory they will be interpreted as hires textures.
//			If a material/shader uses both hires and lores textures the user will get
//			warned.
//			Usually texture nodes don't share the same name with the texture file by
//			default. In this case an asterisk will appear along with the name. Texture
//			nodes can then be set to share the same name with the texture files.
//			The "Get from Selection"-button shows the material from the selected object
//			in the list.
//
//	VERSIONS:
//			2.3 - Jul. 29, 2005
//			- made the global variables more unique by their names
//
//			2.2 - Nov. 17 2004
//			- Fixed the script regarding displacement nodes which are not connected
//			to the shader but the shading-group node.
//			- Fixed the problem with double connections, i.e. when connecting a
//			psdFileTex to the color channel the transparency channel gets connected too
//			- optimized the code when searching the shader tree
//
//			2.1 - Nov. 14 2004
//			- The script will now also work with subdirectories in the sourceimages,
//			lores and hires folders
//
//			2.0 - Nov. 13 2004
//			- Fixed the bug that only texture nodes that directly feed into the shader
//			will get changed; other nodes were omitted and thus the script didn't
//			function properly.
//			- Fixed that after renaming the material gets properly listed.
//			- "Get from Selection" also works now with the default lambert material
