box-drawing: quadrants: convert quad_*() macros to functions

Browse source 
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.
