As has been reported, 1-dimensional horizontal filled polygons are not drawn
at all. That is caused by the scanline algorithm used for drawing filled
polygons which skips the drawing of horizontal edges, because that is
normally not necessary. If, however, the polygon consists of horizontal
edges only, that obviously doesn't work, so we add a special case handling.
That has also been fixed in libgd with
<f9f10fa9>.
Thick lines are drawn by gdImageFilledRectangle(), which iterates over
the x ordinate first (Z order) to apply the style pattern. While this works
fine for vertical and diagonal lines, it obviously fails for horizontal
lines, which have to be iterated over in N order.
To fix this bug, we introduce the helpers gdImageFilled(H|V)Rectangle(),
which may be reused for other purposes as well.
This is basically the same fix as libgd/libgd/c2b91dbc.
The stack overflow is caused by the recursive algorithm in combination with a
very large negative coordinate passed to gdImageFillToBorder(). As there is
already a clipping for large positive coordinates to the width and height of
the image, it seems to be consequent to clip to zero also.

Contrary to imagefilledrectangle(), imagerectangle() has the documented
limitation that the given points have to be the upper left and the lower right
corner, respectively. However, libgd already caters to upper right / lower left
pairs, and not catering to the other two combinations seems to be an oversight.
To avoid drawing the corner pixels twice, gdImageRectangle() draws the vertical
lines 2 points shorter than the actual side of the rectangle. However, this
causes "whiskers" for rectangles with height 0. This patch fixes this issue and
at the same time optimizes the algorithm by drawing only a single line for zero
height and zero width rectangles.
