The bug is in CBitmap::convertToType when converting a DXT1Alpha testure in RGBA.

It's reproductible only when using a .dds texture in a CTextureCube with OpenGL driver because D3D driver is managing by itself the DDS conversion.

We were assuming DXT1 textures always had an alpha channel, which is incorrect.
