I'm sorry Jeff,I should have been paying more attention.

You'll need to make this private and then make a corresponding
TextureManager::SetLevelSize(TextureInfo* info, GLint face, GLint level, GLsizei
width, GLsizei height);

The reason is there is bookkeeping in TextureManager to see if any textures are
breaking any rules. See TextureManager::SetLevelInfo

I took your suggestion, and reverted these changes.  SetLevelInfo is now called
directly from the DoCopyTextureCHROMIUM handler.
