This one's too recursive for anything really complicated (blows the stack). But
it works. You'll find that making it do a border fill instead isn't hard at
all. You'll need to provide your own hLin and scrn routines.

hLin draws a horizontal line from X,to X2,at Y scrn reads the pixel at X,Y and
returns its color color is a global byte variable in this incarnation. The fill
happens in this color.
