Fix bug #72340: Double Free Courruption in wddx_deserialize
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.
- load glyph with FT_LOAD_IGNORE_TRANSFORM for bbox as final bbox is rotated at once later (fixes "double-rotation" per glyph for calculating bbox)
- reload the rotated glyph for painting after that (only if angle != 0)
- rotate the original bbox at 0,0 and do not throw away xMin/yMin (drawing-rotation is also based at "origin" point - including the bearingX, see http://www.freetype.org/freetype2/docs/glyphs/glyphs-3.html#section-3) - this fixes the "left-shift"-problem also when angle = 0
- removed "xb/yb" and use "x/y" directly for offsetting brect (no need for adding "x1/y1" and substracting "yd" later)
- removed therefore unused "yd" helper var which seems tried to fix parts of the original problems
- initialize x/y with 0 instead of -1 in php_imagettftext_common() to make image*text() and image*bbox() results identical (there was a -1px shift in image*bbox() before)
- fixed gdroundupdown() for negative numbers (-256 / 64 gives -5 instead of -4 before)
- rotate kerning-delta by given angle (fixes completely wrong kerning and therefore wrong bounding box if angle != 0)
- changed 3 tests and added a new one to test for the new (better) coordinates
