added the possibility to allocate aligned memory, an use it to allocate the buffer utilized in texture decoding, this will make a little easy to use aligned writes when possible in sse2/3 optimized algorithms.

some code additions for future use ;).
please gcc user test this as i don't have opportunity to test it myself i only use reference code to.
