Fasttracker II clone v1.47

• Bugfix: The Lxx (Set Envelope Pos) XM effect was broken :(
• Added support for loading FLAC samples (w/ loop/vol./name information)
• Added support for loading '8-bit unsigned/32-bit float/64-bit double' AIFFs
• Added support for loading XMs with ADPCM sample compression (ModPlug Tracker)
• The windowed-sinc LUT now has 8192 phases instead of 4096 for a theoretical small interpolation precision improvement
• Bugfix: Fixed a bug with "Save rng." (Smp. Ed.) related to data after/around the loop end point
• "Save rng." (Smp. Ed.) now asks if you want to overwrite an existing file
• Bugfix: The windowed-sinc interpolation was slightly wrong near the loop-start point on looped samples. Was only audible on super-tight loops
• Mixer now uses 32-bit single-precision floats instead of 64-bit double-precision. The error difference in the audio output is +/- 1 (16-bit), which is only -90dbFS and not really audible. This should give a performance boost for devices that are slow with handling double-precision floats.
• Samples now have units of "samples" instead of bytes (in the sample editor). This means that 16-bit samples will show the same numbers as 8-bit samples.
• The sample editor is now drawing interpolated sample points when zoomed in
• Fixed a bug where the "Range" button in Smp. Ed. had problems if you had marked sample data after 65535 sample points
• Fixed a problem where the mouse pointer could be broken in fullscreen mode at some screen resolutions (f.ex. 1600x900)
• Windows bugfix: Prevent ever-increasing memory usage while minimized. Possibly a bug in SDL_RenderClear(). Might've affected other systems too.
• Bugfix: Exit text edit mode when dropping a file onto the window. Fixes possible text cursor overflow issues.
• Bugfix: Some instrument/sample names could contain junk at the end after being saved (.XM/.XI)
• Bugfix: If you previously used an audio device that was disconnected before starting the program, it will now resort to the default audio device without reverting all your audio settings (buffer size, bit depth, frequency).
• Fixed possible crash if a channel's resampling rate/delta was zero (very rare)
• If you copy all the sample data in a sample, it will also copy over the sample information (loop, volume, finetune, name etc.) when you paste it to a new sample
• The "Get maximum scale" button in the "Volume" tool in Smp. Ed. will now get the actual scale instead of limiting it to the start/end vol max range. This means that you need only one pass to normalize the amplitude on a very quiet sample.
• The scopes now use linear interpolation for sample points in "Lined" mode
• Fixed a mistake in the S3M importer where "Set speed" commands with a parameter of >$1F were removed instead of being clamped
• Clearing the instrument (numpad delete key) also clears instrument name now
• Added new keybinding: Press Ctrl + "numpad+"/"numpad-" to increase or decrease the master volume by 16
• Updated the help text
• A lot of variable/function names have been changed to be easier to understand. This causes a mega-commit to the GitHub repo, and I'm sorry for that if you have a fork of it that you want to keep updated. :/
• Code cleanup (big one)
