Revert "In order for dds to save a texture file, its resolution must be a multiple of four (due to recent engine change which uses hard coded relative texture size instead of ddssize argument) -- This may just be a workaround, but either way it's totally harmless (just resized 1x1 texture files to 4x4 texture files). A real solution would later be a new model which has a real texture." WRONG. This is an engine bug and by doing this workaround, we lose the chance to solve it. Reverting.

This reverts commit c5d711414f9bcf2835e2cead0082454c9976f533.
