Changed naming of "average volume" to "peak volume" to more accurately describe what is being done/represented Removed the divide by 2 in calc_peak_volume so that the second half of the samples would also be factored when calculating the peak volume in the most recent sample data Changed references to 128 to use the SDL_MIX_MAXVOLUME preprocessor definition for clarity Changed the line that caches the peak volume in input_callback to use sizeof(int16_t) instead of 2 for clarity Changed input_callback to use a local buffer of size XBLC_FIFO_SIZE instead of allocating one at runtime Changed the get/set volume functions in xblc.h and xblc.c to use floating point values on the interval [0, 1] instead of integers on the range [0, SDL_MIX_MAXVOLUME] because they're used that way everywhere else anyway Changed the numOutputDevices variable in DrawAudioDeviceSelectComboBox function to num_devices to match the naming scheme and because this function doesn't only work with output devices. Changed xemu_input_bind to use an if statement instead of a switch. The switch was left behind from before I added the xemu_input_unbind_peripheral function when I was calling xemu_input_unbind_xmu and xemu_input_unbind_xblc directly
