// MediaIcon.h (Cortex/Support)
//
// * PURPOSE
//   
//   Easy construction of an icon-representation for common 
//   kinds of nodes
//
// * NOTES
//
//	 5dec99 i've included some workarounds for the buggy GetDormantNodeFor()
//			 function
//   24oct99 simple to use but *not* very efficient!
//
// * HISTORY
//   c.lenz		17oct99		Begun
//	 c.lenz		5dec99		Bugfixes & support of application icons
