Implement sub 8x8 tile encoding. Fixes incomplete mipmap chains which previously only went down to 8x8 pixels before. It wasn't known these textures existed before. (Harry Tuttle)

Fix some bad/missing textures in fighting vipers. The game is referencing totally illegal texture sizes. The real h/w was just handling it somehow, whilst we were returning null for the textures. This might produce junk textures for the lower mipmaps, but this can be clamped in a later update.

The mipmap data in some games seems to being sent behind the base textures, and when the base textures are bound and created the mipmap chain is not yet valid in memory. To fix this, we invalidate the base textures, when the mipmap chain is updated.

Originally to do mipmapping, I just used the base texture and then let the h/w automatically generate the mipmap chain. I wasn't sure the real3d api even exposed to the programmer the ability to directly set the mipmap data. Anyway, as pointed out by HarryTuttle scud actually uses darker mipmaps for an effect on the water. This patch uses the uses the actual mipmap data from the real3d memory. Only tested scud, so hopefully I didn't cause any cataclysmic errors :)

Need to walk back in memory and check the previous texture tiles to see if they overlap with the current textures being invalidated. If they overlap they must be cleared too. Algorithm is a bit brute forcy and more expensive than I'd like but it fixes the bad textures in Spikeout.
