--------------------------
Changes in 1.9 (not yet released)
- Add function IVideoDriver::queryTextureFormat to allow checking if a driver supports textures with a specific color format.
- ISceneManager::getMesh can now creates meshes with alternative cache-names.
- Lets the BSP loader find textures inserted with relative paths. Thx@ curaga for patch
- Slightly simplified ALLOC_STRATEGY_DOUBLE in arrays
