Fix #64641: imagefilledpolygon doesn't draw horizontal line
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
<https://github.com/libgd/libgd/commit/f9f10fa9>.
Fix #43475: Styled thick horizontal lines are scrambled
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.

Fix #50845: exif_process_IFD_TAG: Use the right offset if reading from stream
Fix bug #72138 - Integer Overflow in Length of String-typed ZVAL
Fix #50845: exif_process_IFD_TAG: Use the right offset if reading from stream
When the location of the data is outside of the range we have
preloaded (for example, if it's before the beginning of the IFD
structure), we have to read it from the stream into a separate buffer.
The offset calculations in this case were incorrect, resulting in
bogus values being read for the affected fields (sometimes parts of
other fields, sometimes binary data).
The included test image, sourced from [1], is in the public domain.
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.
