Changelog:

  - 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()
    functions

Errata:

  - 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
    scaling
  - 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.
