Segfault was due to `glyph_position` structs keeping a pointer to
`glyph_info` objects which went out of scope at a different time.
The (rather ugly) fix for the moment is to copy that information
into the thunk object.
- there are two versions:
- point-symbolizer-expressions: file
- point-symbolizer-expressions-all: additionally test
allow-overlap, opacity, transform, ignore-placement, comp-op
which are not supported right now
- there are two versions:
- polygon-symbolizer-expressions: fill, fill-opacity, gamma
- polygon-symbolizer-expressions-all: additionally test
comp-op which is not supported right now
- there are two versions:
- line-symbolizer-expressions: stroke, stroke-width, stroke-opacity, offset
- line-symbolizer-expressions-all: additionally test
stroke-dasharray, stroke-linecap, stroke-linejoin, comp-op
which are not supported right now
These are mostly text affected because it is multi-line. The
"lines-5" test case text is improved - it lines up now. The
"line-offset" test case is not multi-line, but the differences
appear to be minimal.
Calculation of label alignment in multi-line labels seems to be
off. This test reproduces it by laying out a series of multi-line
labels along an S-shaped curve. In all these cases, the vertical
bar character should, to within a few pixels, line up. The
orientation at sharper corners is still a little off, but likely
due to discontinuities.
Both are rendering the same SVG marker, at the same size. The
output should (and does, for Cairo & Grid renderers) look like
identical rows of spots. But the AGG one does not.
This is an attempt to create a test case for issue #2117.
