53fe825e49 Add first pass of atomic implementation.
This is a first pass of what I believe to be a not too terrible
implementation of a cooperative thread-based compressor. The idea is
simple... If a compressor is invoked with the same parameters on multiple
threads, then the threads cooperate via an atomic counter to compress the
texture. Each thread can take as long as possible until the texture is finished.

If a caller calls a compression routine that has different parameters, then
it will help the current compression finish before starting on its own compression. In this
way, we can split the textures up among the threads and guarantee that we maximize the
resource usage between them. I.e. this becomes more efficient:

Thread 1:    Thread 2:   Thread N:
  tex0         texN        tex(N-1)N
  tex1         texN+1      tex(N-1)(N+1)
  ..           ..          ..
  texN-1       tex2N       tex(N-1)N

I have not tested this for bugs, so I'm still not completely convinced that it is deadlock-free
although it should be...

ca85a663a1 Add detection for atomics
Atomic operations are both supported by the platform and the compiler. If we want
to provide a threadsafe implementation of our compression function, we need to make sure
that the proper settings are available.

ff1c3658fb Always set all of the compiler warnings on and make sure to include the MSFT extensions if we're on gcc. Furthermore, include an option to treat warnings as errors. I will probably always have this on, but other people who decide to use the library probably won't want it... 2013-01-28 18:11:29 -05:00
