ProTracker v2.3D clone changelog:
NOTE: This may contain stuff that only a programmer understands!

Beta #29 - 06.08.2019
- Added a HWMOUSE config entry to protracker.ini (toggles hardware mouse)
- VU-meters and the "spectrum analyzer" now sink in 50Hz like on Amiga

Beta #28 - 29.08.2019
- A few quadrascope bugfixes
- Updated pt-clone.sln (Visual Studio 2019 project)

Beta #27 - 05.08.2019
- Removed SSE macros to let the compiler optimize instead, and to make cross
  compiling even simpler.
- macOS: Fixed intensive CPU usage if another window is completely covering the
  PT clone window.
- macOS: The SDL2.framework file in the PT clone app was larger than it needed
  to be, which was fixed by the SDL team not long ago. It has been replaced.

Beta #26 - 19.07.2019 (updated 29.07.2019)
- Bugfix: When clearing the song, the unmute buttons didn't redraw properly
>> 29.07.2019:
- Bugfix: pt_unicode.c wouldn't compile on other systems than Windows
- SDL updated from v2.0.9 to v2.0.10
- Removed the old MinGW make file/include stuff

Beta #25 - 21.06.2019 (updated 09.07.2019)
- Bugfix: When loading 15-sample .MODs (SoundTracker etc), samples above
  0xF (15) were somehow linked to sample #1, and editing them would ruin
  the first sample (!).
- Bugfix: Filenames were accidentally not sanitized before saving in
  beta #24. This would result in some files not being saved depending on
  the song/sample name and the filesystem in use in your OS.
- Updated help.txt to contain more details about the PAT2SMP feature
- Some minor code changes and cleanup
>> 09.07.2019:
- Removed a GCC compiler warning :)
- Windows: Edited the Visual Studio project to generate a debug database in
  release mode, which is handy for debugging.

Beta #24 - 20.06.2019
- Bugfix: CTRL+W (Polyphonize block) was broken
- Bugfix: The "Mod" (modulate) effect in Edit. Op. #3 was broken.
  This also messed up "Echo" if Mod!=0 while using it.
- Added support for loading 64-bit floating-point .wav files
- Added support for loading (uncompressed) .aiff files
- Big Endian support has been removed, as I don't want to spend time
  testing endianness every time I add a new change that could need it.
  I don't think a lot of people will run SDL2 programs on big endian
  systems anyways, especially not this program.
- Updated help.txt
- Major code cleanup. Including: Proper space alignment for special tab
  indents, removed extreme use of parenthesis, spaces etc.

Beta #23 - 23.04.2019 (updated 26.04.2019)
- Key repeat/delay values were wrong, so the pattern cursor movement
  would be too sensitive/fast (and other keybindings).
- Updated keyboard.txt
>> 26.04.2019:
- Key repeat (Caps Lock) is now set to the initial Caps Lock state when
  the program is started.

Beta #22 - 21.04.2019
- Fixed a bug where the "Set Multi-pos" keys (Alt+1..4) would interfere
  with "Insert Stored Command" keys (ALT+0..9) in edit/rec. mode.
- Code cleanup

Beta #21 - 18.04.2019
- If you have unsaved changes and are about to load a new module, ask if
  you want to discard all changes.
- Windows: Updated SDL to version 2.0.9 (finally found a way to prevent a
  serious bug with 2.0.9, hence why I have been using 2.0.8 for a long time).
- Windows: Default Disk Op. directory is now "\Users\username"
- Fixed a small bug where the "SELECT MODULE" text would sometimes not
  appear when you click on "DISK OP.".
  
Beta #20 - 09.04.2019
- Some small scope fixes

Beta #19 - 03.04.2019
- Fixed pattern notes not being the same on all keyboard layouts
- Fixed: "The Ultimate SoundTracker" .MOD import was broken since beta #2
  (10.11.2018).
- Maximize (restore) the window if a sigterm is received before the program
  asks if you really want to quit.
- Small code cleanup
- Edited "keyboard.txt"

Beta #18 - 30.03.2019 (updated 30.03.2019)
- Further fixing to prevent more possible stutter with vsync (60Hz monitor)
  on some monitors (rare case).
>> 30.03.2019:
- Sometimes the mouse would be off center when toggling fullscreen mode
- Forgot to round when doing mouse scaling

Beta #17 - 29.03.2019
- Scope rate has been changed from 60Hz to 64Hz to prevent random stutters
  on some systems because of timing interference. If your monitor is not
  running at 59Hz/60Hz, they will stutter anyways.
- Scopes are now behaving more like PT2.3D (e.g. don't show vibrato and arps)
  to make it overall look more smooth and stable.
- The "Amiga 500" filter mode now has a slightly higher low-pass filter cutoff
  to sound closer to an A500.
- The "resample" function in the Sampler screen didn't work! Oops!
- The audio mixer is now using double-precision float (64-bit) instead of
  single-precision float (32-bit). Placebo mode activate!
- Split help.txt into help.txt, effects.txt and keyboard.txt

Beta #16 - 22.03.2019
- Effect EDx (Note Delay) had a bug where it would instantly set the
  new note's pitch without delaying. This bug has been present since
  23.11.2018 (Beta #2). Sorry!

Beta #15 - 18.03.2019
- Added a new config entry called "HIDEDISKOPDATES", used to hide the
  last modification date in Disk Op. to get more room for dir/file names.

Beta #14 - 17.03.2019
- Fixed a sampler screen bug where the sample data could be incorrectly
  rendered in the very right corner when zoomed out.
- Don't allow drag'n'drop while a volume/filter toolbox is open (sampler)
- Code cleanup (code style is looking more like the FT2 clone now)

Beta #13 - 13.03.2019
- Fixed some fullscreen-bugs with the mouse when using two or more monitors
  with different screen resolutions.

Beta #12 - 11.03.2019
- The 32-bit Windows version of the PT clone no longer requires the SSE2 CPU
  instruction set to function.
- Fixed a bug where some PT-Config.xx files could not be loaded
- Tiny code cleanup

Beta #11 - 25.02.2019 (updated 27.02.2019)
- Touchscreen input should now work properly in fullscreen mode
>> 27.02.2019
- Tiny code cleanup (and Visual Studio project file change)

Beta #10 - 14.02.2019
- Mouse scaling was 100% broken on Macs with retina displays (high-DPI).
  Sorry! This is fixed now.
- No need to do floating point operations on mouse coord scaling!

Beta #9 - 11.02.2019
- Mouse position was incorrectly scaled in fullscreen mode (the coursor wouldn't
   move in the correct speed in some cases).
- Code cleanup

Beta #8 - 18.01.2019 (updated 30.01.2019)
- Fixed a delta/rate bug in the replayer (used lastDelta instead of Delta)
- When in idle mode (not edit/play/rec.), ALT+1/2/3/4 is now used to change
  Multi ordering (Multi = CTRL+M).
- Updated screenshot.png and help.txt
>> 30.01.2019
- Code cleanup

Beta #7 - 14.01.2019
- Don't enable SDL2 text input when it's not needed. Potentially removes
  ~2ms spikes on every key press.
- No need to initialize SDL2 timers when we don't use them anymore!

Beta #6 - 10.01.2019
- Added a config option to turn off vsync
- WaitVBL() function for scopes and video (when no vsync) has been changed to
  include fractional precision for "next frame time" counter. Note that this
  is a minor change and does not magically remove video stuttering.

Beta #5 - 29.12.2018
- The playback timer is now counting BPM ticks from the replayer
  instead of spawning/deleting a 1-sec SDL timer every time you
  play a song.

Beta #4 - 28.12.2018
- Fixed an issue with sample data peaks while zooming in/out in the sampler
  screen.
- Fixed a rounding issue in sample data marking in the sampler screen

Beta #3 - 23.11.2018
- Support loading MODs with 1, 2 or 3 channels
- Channel muting now works like in original ProTracker
- Fixed linear interpolation edge case on resampler/chord maker
- Small code cleanup

Beta #2 - 10.11.2018
- Sample sizes are now limited to 64K, like real PT (sorry, but I want to keep
  it PT2.3D-accurate)
- Removed monoscope
- Fixed some graphics to suit the 64K limitation (and added Noxious string etc)
- Fixed some bugs in the sampler screen (possible beep when playing
  disp/waveform, marking bugs, etc)
- Small code cleanup
- Updated help.txt

Beta #1 - 04.11.2018
- Added beta version string to window title and about screen
