A brush can hold a lot of settings like multiple texture layers, color, alpha etc. It seems like Brushes are the "real texures" while Loadtexture and TextureEntity are dead end commands.
Example: if you want to save a Mesh with Textures (eg. the SaveB3D Example in the code archives), they need to use Brushes to allow to determine the used Texture Files etc.
An other example:
You can load a Mesh, check its brushes for a special Texture, and then replace this brush by an other brush that has a diffrent number of texture layers.
