/* ok, coming up with procedure:
* - can't rely on bg_stripes; line count, threshold, etc., will need to happen here
* - line count will always be the largest multiple of 6 smaller than height; c = h - (h % 6)
* - chevrons may have larger widths: TODO calc
* - depth will be funky; line depth will need to use "full" depth; (Df - Dl) / Wc = Ic (TODO verify?)
* - switch stripe index on *absolute* line number rather than n
* - chevron building will be BLOCK.repeat(width) + TRIANGLE_21[0] (fg Ic, bg Ic + 1)
* - chevrons[len - 1] will need unique handling to draw stripes
