Must release texture data because of the following scenario (common!)
- An IG with 2 different meshs is async loaded
- the 2 meshs access the same texture "pipo.tga"
- in CAsyncFileManager3D::loadMesh(), if this case arise, the
textures are loaded twice in RAM!!!! (is managed per mesh, but not
thourhg meshs)
- hence the first mesh setup and upload above the texture in VRAM
but the second still have data in RAM!! (because 2nd will
say that isTextureExist() ....
Note: you could say that the cool stuff would be to not load the 2 :)
but it appears that this case arise rarely because of the following statement:
- while the second mesh is async loaded, the first upload in VRAM
so there is good change that the second don't load the texture
