      Added LICENSE.txt and GPLv3.txt. Also updated libco documentation.
      After discussion with byuu, libco gets a more specific ISC license
      to match nall, ruby and hiro. higan, as clarified in LICENSE.txt,
      continues to be GPL version 3 only (no "or later" clause).

      Fixed: Restore SPC7110 and S-RTC time properly · a9571ff5
      Talarubi authored
      Loading and unloading the RTC is a little odd, since it's normally
      always powered in the first place. What we want, and what the load()
      functions really do, is to resync using the saved timestamps or
      reset it. unload() proper doesn't do anything.
      However, an interface refactoring after v098 reordered the above
      operations, and this (along with a typo, shh!) was causing the already
      synced time to be cleared.
      I've added checks so that whenever rtc.ram can't be found, load() gets
      called with empty arguments to initialise the defaults (like putting
      in a fresh battery).

      byuu says:
        - processor/huc6280,mos6502,wdc65816: replaced abbreviated opcode
          names with descriptive names
        - nall: replaced `PLATFORM_MACOSX` define with `PLATFORM_MACOS`
        - icarus: added `Icarus::missing() -> string_vector` to list missing
          appended firmware files by name
        - ruby, hiro: fix macosx→macos references
      The processor instruction renaming was really about consistency with the
      other processor cores. I may still need to do this for one or two more
      The icarus change should allow a future release of the icarus
      application to import games with external SNES coprocessor firmware once
      again. It will also allow this to be possible when used in library mode.

        - hiro/cocoa: fixed typo [Sintendo]
        - hiro/Windows: removed GetDpiForMonitor, as it's Windows 8+ only; DPI
          is no longer per-monitor aware

          directory::create, <file::exists>, <file::copy>, <file::write>

        - nall/GNUmakefile: build=release changed to -O2, build=optimize is
          now -O3
        - hiro: added Monitor::dpi(uint index) → Position [returns logical
          DPI for x, y]
            - Position is a bad name, but dpi(monitor).(x,y)() make more sense
              than .(width,height)()
        - hiro: Position, Size, Geometry, Font changed from using signed int
          to float
        - hiro: Alignment changed from using double to float
        - hiro: added skeleton (unused) Application::scale(), setScale()
        - hiro/cocoa's Monitor::dpi() is untested. Probably will cause issues
          with macOS' automatic scaling.
        - hiro/gtk lacks a way to get both per-monitor and per-axis (x,y) DPI
        - hiro/qt lacks a way to get per-monitor DPI scaling (Qt 5.x has this,
          but I still use Qt 4.x)
            - and just to get global DPI, hiro/qt's DPI retrieval has to use
              undocumented functions ... fun
      The goal with this WIP was basically to prepare hiro for potential
      automatic scaling. It'll be extremely difficult, but I'm convinced that
      it must be possible if macOS can do it.
      By moving from signed integers to floats for coordinates, we can now
      scale and unscale without losing precision. That of course isn't the
      hard part, though. The hard part is where and how to do the scaling. In
      the ideal application, hiro/core and hiro/extension will handle 100% of
      this, and the per-platform hiro/(cocoa,gtk,qt,windows) will not be aware
      of what's going on, but ... to even make that possible, things will need
      to change in every per-platform core, eg the per-platform code will have
      to call a core function to change geometry, which will know about the
      scaling and unscale the values back down again.
      Gonna be a lot of work, but ... it's a start.

        - sfc/ppu/background: hires mosaic seems to advance pixel counter on

        - tomoko: added “Help→Credits” menu option (currently the page does
          not exist; should before v105)
        - tomoko: reduced volume slider from {0% - 500%} to {0% - 200%}.
          Distortion is too intense above 200%.
            - technically, I've encountered distortion at 200% as well in
              Prince of Persia for the SNES
        - nall/run/invoke: use program path for working directory
            - allows you to choose “Library→Import ROMs” from a different
              directory on the command-line
      I don't know how to assign credit for the mosaic stuff. It's been a
      work-in-progress with me, Cydrak, and hex_usr.
      The current design should be correct, but very unpleasant. The code
      desperately needs to be refactored, but my recent attempt at doing so
      ended in spectacular failure.

      Turns out there is only one mosaic size, and the other four bits are
      per-BG mosaic enable. This matters a lot for hires/interlace, as
      mosaicSize=0 (2x2) is not the same thing as mosaicEnable=false (1x1).
      Although I've now implemented this, I really don't like how my mosaic
      implementation works right now. I tried to redesign the entire system,
      and completely failed. So I started over from v104r10 again and instead
      went with a more evolutionary improvement for now. I'll keep trying.
      Also, the combination of mosaic + offset-per-tile is still sketchy, as
      is mode 6 offset-per-tile. I'll get to those in the future as well.

        - resource: recreated higan+icarus icons, higan logo as 32-bit PNGs
      So higan v104r08 and earlier were 930KiB for the source tarball. After
      creating new higan and icarus icons, the size jumped to 1090KiB, which
      was insane for only adding one additional icon.
      After digging into why, I discovered that ImageMagick defaults to
      64-bit!! (16-bits per channel) PNG images when converting from SVG.
      You know, for all those 16-bit per channel monitors that don't exist.
      Sigh. Amazingly, nobody ever noticed this.
      The logo went from 78.8KiB to 24.5KiB, which in turn also means the
      generated resource.cpp shrank dramatically.
      The old higan icon was 32-bit PNG, because it was created before I
      installed FreeBSD and switched to ImageMagick. But the new higan icon,
      plus the new icarus icon, were both 64-bit as well. And they're now
      So the new tarball size, thanks to the logo optimization, dropped to
      Cydrak had some really interesting results in converting higan's
      resources to 8-bit palletized PNGs with the tRNS extension for alpha
      transparency. It reduces the file sizes even more without much visual
      fidelity loss. Eg the higan logo uses 778 colors currently, and 256
      represents nearly all of it very well to the human eye. It's based off
      of only two colors, the rest are all anti-aliasing. Unfortunately,
      nall/image doesn't support this yet, and I didn't want to flatten the
      higan logo to not have transparency, in case I ever want to change the
      about screen background color.
