Detailed Description
Async Loader of textures and Texture Load Balancer.
Additionaly, store in RAM for each texture load a very low, DXTC1 compressed version of the texture. Used for some Lod systems. -

Add a reference to a texture owned by an instance.
If the texture still exist, only the refcount is incremented Else If texture is found in the HLSTextureManager, it is builded (async) from it, else Begin Async loading
ThereFore, only CTextureFile are possible. Note also that the texture is uploaded with mipmap by default, and UpLoadFormat is also default (say ITexture::Auto)
If the texture file is not a DDS with mipmap, this is an error. But the system doens't fail and the file is entirely loaded and uploaded. The problem is that upload is not cut according to maxUpLoadPerFrame, so some freeze may occur. |

get the RAM LowDef version of a texture.
Used For CLodCharacters return NULL if bad Id or if the texture is still not loaded. The bitmap returned has no mipmaps and should be in DXTC1 (not guaranteed).

setup the mipMap levels.
\baseLevel When the texture is first added, it is loaded skipping the baseLevel first mipmap \maxLevel During time, furhter mipmap are loaded, according to instance position etc... maxLevel tells where to stop. If 0, the texture will finally be entirely uploaded. Default is 3,1.
