Currently Tracy assumes that users will be posting screenshots of frames via the tracy::Profiler::SendFrameImage API. Because of this Tracy starts an additional thread and includes code for performing on-the-fly DXT1 texture compression. Since we never need this it'd be nice to be able to toggle all of that off to reduce the code size impact and extra runtime threads.

HLS often uses arbitrary precision arithmetic. In this model, most operations (e.g. add, multiply) have wider results than their input, in order to represent all the possible result values without overflow. Explicit Truncation operations are necessary in order to limit the growth of values. The rules are roughly:

bitwidth(a + b) = max(bitwidth(a), bitwidth(b)) + 1
bitwidth(a - b) = max(bitw
