This is necessary in order to be able to correctly translate between absolute and relative paths
deeper in the code - e.g. paths to SVG files used in marker or fill symbols.
Until now, relative paths were translated to absolute paths on the fly.
This is now changed - paths to files should be always absolute within QGIS objects - and paths
only get turned into relative when saving projects. When loading a project, relative paths
are translated to absolute paths immediately.
This should lower the overall confusion about relative/absolute paths within QGIS, and also
allow having different base directories for relative paths (e.g. QML or QPT files may use relative paths
to their directory - rather than to the project directory)
This change is being driven by:
- need for consistent terminology in the api. Currently there's
a confusing mix of border/outline used
- need for consistent terminology in the gui - we have a mix
of "border"/"outline"/"pen"
- bringing QGIS into line with the standard terminology used
in other graphic editing programs
copy/= operators or making them private
This revealed (and fixes) some issues, including a potential crash
using server access control (refs #13919), and a potential crash with
diagrams
...and update all bundled SVGs to suit
Non-bundled SVGs must add:
fill-opacity="param(fill-opacity)"
and
stroke-opacity="param(outline-opacity)"
to enable transparency support
reset the fill/border color and border width when changing svg
marker/svg fill SVG files
This change makes the behaviour consistent between the svg marker
symbol and the other marker symbols. Additionally, svg files
which have customisable colors and NO default values set will
be shaded in gray fill/black outline in the svg selector widget,
to follow the same behaviour as the other marker symbol selectors.
Note that this change has NO EFFECT unless the svg files are
modified to remove the default param value, so there will be no
change for users' custom symbols. A follow up commit will need
to remove the default param values from the preinstalled SVG
files though. If you want to test in the meantime, I've modified
just the first two symbols in the accomodation group to make
this change for testing.
(refs #10908)
The crashes would happen after some time when browsing the map,
especially when size of SVGs is in map units. This was due to wrong
removal of deleted cache entries where cache entry key would be
different from SVG file's path, thus not removing the entry that
got deleted. Now explicitly keeping the lookup key in the entry
to make sure this does not happen.

- Fix#6855, SVG markers/fills larger than half cache (559^2 X 32 + SVG) are drawn with QPicture
- Fix#6861, make QPicture SVG symbols scale with Composer page zoom
- Fix#6861, make SVG symbol output to print/image more accurate by setting 'size' to double
- Update/add support for non-squared SVG via QImage and QPicture, on screen and in output to print/image
- Non-squared SVG QImage/QPicture can now be used in pattern fill, without excess space
- update methods of existing classes
- add comment to methods missing in the sip bindings
- split up collective sip files into single files and use
same directory structure in python/ as in src/
- add a lot of missing classes (some might not make sense because of
missing python methods in those classes)
- remove some non-existing methods from the header files
- add scripts/sipdiff
- replace some usages of std::vector and std::set with QVector/QSet
