box-drawing: {h,v}line: implement using pixman
...
Use pixman_image_fill_rectangles() to render horizontal and vertical
lines.
Despite the name, this *is* the appropriate function to use, since our
lines *do* have a thickness, and thus *are* rectangles.

Both are functionally equivalent here, but the former is also properly
scoped, can be naturally indented and has a less repetitive syntax.

If the value is specified without a unit, then the value is assumed to
be in points, subject to DPI scaling.
The value can optionally have a ‘px’ suffix, in which case the value
is treated as a raw pixel count.

box-drawing: drop ‘pragma GCC optimize(“Os”)’
...
“The optimize attribute should be used for debugging purposes
only. It is not suitable in production code.”
Luckily, it seems it really isn’t needed anymore; with all the other
size optimizations that has been done since this was introduced, there
is no longer any difference with or without this pragma.

match the thickness of an abstract, orthogonal line going through the
middle of the cell.

box-drawing: LIGHT ARC: simpler way to adjust for asymmetrical arc when mirroring
...
When mirroring an arc, we need to adjust the mirrored position if the
arc’s position in the cell is asymmetrical. This happens when *either*
the line is odd sized, *or* the cell is. But not when both are.
Thus, we can simply do a ‘thickness % 2 ^ width % 2’ when adjusting
the position.
Describe this in a comment.

box-drawing: quadrants: convert quad_*() macros to functions
...
This reduces the size of the foot binary by ~4K; all the quad
macros called ceil() and floor() twice per macro, which caused many
float -> int -> float conversions in the expanded code.
By using functions instead, there’s no expansion - the conversion only
happens in one (well, four) places.

box-drawing: reduce number of function arguments
...
We were using so many function arguments that a lot of the emitted
code was just stack push and pops to pass around arguments.
Bundle the buffer data, width, height, stride, and current DPI, into a
single ‘buf’ argument. This greatly reduces the number of arguments to
all functions.
