[Development] qdds image format

[Иван Комиссаров]

At the point i wrote the plugin, my usecase was simple - to convert plain
QImages to and from DDS icons (used in starcraft2, which uses quite a few
formats DDS can handle).
But yes, i forgot floating point textures.
Compressed textures (DXTN/ATI2) are just compressed (a)rgb32, nobody uses
compressed jpeg, it is decompressed before usage (correct me if i'm wrong,
but videocards uses DDS because it's decompression algorithm can be easily
implemented in hardware)
