Consolidated audio processing code into the PCM class, removing the BeatDetect class in the process. Beat detection now uses the same algorithm as Milkdrop, passing the proper relative bass/mid/treb values to presets. Makes many presets look less jumpy/flickering, as the values are now (smoothly) alternating around 1.0.
Updating frame audio is now done in a function that must specifically be called. Any subsequent calls to GetFrameAudioData() will then return the exact same copy of the audio data. As of now with the exception that new waveform data may be passed in via a separate thread, which will then be returned and might not match the spectrum data. Will fix that in a later commit.
Some members and functions were named in different ways, now the naming scheme is a bit more unified. Also changed some types to size_t where negative values don't make sense.
* Beat detect sensitivity fix.
* Default: 1.0
* ReadMe beat sensitivity min/max.
* Beat sensitivity from config or settings isn't initialized.
* Smarter position.
* Make PCMScale (vol_history) also impacted by beat_sensitivity.
* Enhance and clarify Hard Cuts and better separate beat sensitivity.
* Forgot one config.
* Consistency with defaults.
* Even more clear about the default for Beat Sensitivity.
* There was a bug that existed in open GL ES 2.0 implementations
where glTexImage2D could not convert GL_RGB formed textures into GL_RGBA
while generating the noise textures. The GL error
was GL_INVALID_OPERATION(0x502)
This probably made the noise textures blank.
So a new class was added that has the alpha channel for the values.
* Added a fudge for render farming milkdrop where we control the time and the ticks.
* User defined time: Got rid of testing code
* Attempt to fix WIN32 compile - it doesnt use or need the ability to control the time
* Got rid of debug - got rid of minor warning
* projectM.hpp - type in ifdef
projectM_SDL_main.cpp - there is code added to make the initial random number dependent on the time of day, making
the sequence of visualizers more unexpected. But the posix command time does not exist in Win32 land, so we disable it.
