gfx.py - fill_triangle broken for flat topped triangles

[jeffmer]

Lines from 199 in fill_triangle should be:
sa = 0
sb = 0
if y1 == y2:
last = y1
else:
last = y1-1
y = y0
while y <= last:
which is a better translation of the original Adafruit c -code
needs y+=1 at end of loop

[kattni]

This appears to have been resolved.

I'm facing the same issue on my repo,
when y coordinates of 2 points are the same, it fills the triangle all the way up,

First picture is when I call
display.fillTriangle(400, 150, 300, 100, 400, 100, display.BLACK)
and the second is when
display.fillTriangle(400, 150, 300, 101, 400, 100, display.BLACK)
is called.
