It helps not to dwell on the X implementation too long.  You should
select whatever interfaces appear the most suitable on Windows, so long
as the logic around when to display stipples is preserved faithfully.

On Android, for instance, the relevant code exists in two functions
defined in EmacsGC.java, prepareStipple and blitOpaqueStipple, which are
nothing akin to the X implementation it emulates.  The same is true of
haikuterm.c, haiku_draw_stipple_background, and BView_DrawBitmapTiled in
haiku_draw_support.cc.
