// This file was originally written by ZDimitor.
// I (Nikolaus Gebhardt) did some few changes to this:
// - replaced logging calls to their os:: counterparts
// - removed some logging calls
// - enabled image dropping of CImage again, because that bug has been fixed now
// - removed setTexture path and replaced it with the directory of the mesh
// - added EAMT_MY3D file type
// - fixed a memory leak when decompressing RLE data.
// - cleaned multi character constant problems with gcc
// - removed octree child scene node generation because irrlicht is now able to draw
//   scene nodes with transparent and sold materials in them at the same time. (see changes.txt)
// Thanks a lot to ZDimitor for his work on this and that he gave me
// his permission to add it into Irrlicht.
