This fixes a couple of subtle rectangle select behaviors:
* Corrects how selection rolls over when crossing the x-boundary; this
was mentioned in #1021, this properly corrects it so both sides of the
x-boundary do not share characters.
* Corrects a minor quirk in the selection of initial cells in a
selection - this can be more readily observed when selecting a single
line with rectangle select. To correct this, we only use the x axis
when calculating this instead of both x and y.
Some box codepoints (the cursor) want to use the original font metrics
height but others (corners) want to use the full grid height. I can't
see a better way to do this than manually maintaining a switch here. We
can add codepoints as needed.
Add additional keypad keys to the encoding scheme. This allows Ghostty
to report KP_HOME and it's relatives. We also always check for a keyval
first, so we can report KP_7, etc as opposed to ASCII '7'.
GTK doesn't expose the num_lock state via the key press event, this must
be obtained directly from the device. Set the num_lock state in the
modifier mask. This also will never show up as a `consumed_mod`, so we
don't bother setting it there.

This adds support for the equalize_splits feature that's already
implemented for macOS.
It's essentially a port of the Swift implementation, using the same
weights-mechanism to equalize split sizes.
terminfo and shell integration files can be installed on a headless server without copying all
of Ghostty to the server. Implementation liberally cribbed from the Kitty Nix package.
Further to the additional comments in #1055, this adds some references
to the comments in the ellipse algorithm (including the original
reference for the circle algorithm).
This changes the half-circle drawing algorithm for glyphs E0B4 and E0B6
to an ellipse algorithm.
This fixes a shortcoming in the circle approach - how do you handle
drawing for a box that is not a typical 2:1 H*W? We were trying to
anticipate this by taking the smaller of the two axes and using that for
the radius. This works when there's some error in the zoom and the x
radius somehow becomes larger than the y radius (in observation, this
happens occasionally in some zoom steps, but only slightly).
However, turns out a more realistic anticipation is for fonts that have
a much *larger* height-to-width ratio. Iosevka, for example, has an
approx. 2.6:1 ratio (observed in the inspector). In this instance, this
approach does nothing except lock the circle to an extremely small
radius. For this instance, we need an ellipse, which will handle all
cases in an expected fashion.
Fixes#1050.
