SoLoud "SLF" Milestone Release

• Hilights:
  • New demo: "space", demonstrating visualization data from different parts of the pipeline
  • New demo: "pew pew", demonstrating difference between play() and playClocked()
  • New filter: flanger
  • New way to play sounds: playClocked() for rapidly-launched sounds, to make it so all sounds don't start from the beginning of a sound buffer
  • Loop count query added
  • Voice groups to command several voices in one atomic operation
• A lot of variable type changes:
  • Defined error codes, and several functions return error codes now.
  • Time variable type changed from float to double
  • Typedefs for handles, time, result codes
  • Plenty of "int" -> "unsigned int" changes, some ints changed to bools
• A lot of work on code generation and wrappers:
  • Codegen now also outputs soloud_codegen.py with all data needed to generate wrappers
  • Python wrapper generator
  • Python API
• Other changes that affect your code:
  • stopSound() renamed to stopAudioSource(). Audio sources also got a new stop() function that stops all instances.
  • Echo filter now has an optional low pass filter to make more "natural" echoes
  • Default post-clip scaler upped from 0.5 to 0.95
  • New songs for multimusic, changed multimusic to use voice groups
• Regarding builds:
  • Redesigned the mechanism by which different backends are included in the build, controlled mainly through premake
  • Many new premake options
  • "nondyn" SDL build added which links to SDL directly, for special needs such as emscripten
  • sdl2 dll may work now (mutex functions were renamed from SDL to SDL2, audio API should be almost the same)
• And, under the hood:
  • Side project - resamplerlab - to make writing new resamplers easier, with some experimental resamplers
  • Some work towards osx, linux compatibility
  • FFT code moved to its own source so it can be more easily replaced in the future
  • Changed mixer fixed point from 16.16 to 12.20
  • Various small fixes, as usual.
