because using this more consistently throughout the codebase makes it
easier to maintain code.
We also do not want to call the copy constructor on them, using pointers
just makes this more obvious. Further, casting is also something
that's commonly done on pointers and not references.
And if you want a value or a reference, just use QgsGeometry, it's meant
to be handled like this.
* use AUTORCC to avoid locked qrc_images.cpp during build of gui tests
* bump minimum version of cmake to 3.0.0 for AUTORCC
* suppress some warnings in sip bindings
* suppress unreachable warnings and some more
* split sip files in more parts to suppress warning BK4504
* also remove old WITH_INTERNAL_YAML from travis
1. endless loop when a sqlite-based layer is opened, and
wal+shm files are created. This triggers a loop because
the directoryChanged signal is emitted again and again ...
This was the real blocker.
2. when a new files appears in a directory
the directoryChanged is emitted and OGR/GDAL may fail
to open the file because the file copy was not yet
finished.
This commit fixes 1 but the fix for 2 is only a best effort using
a 100 ms timer: I could not find a definitive solution to this issue,
a file could be legitimately opened in streaming mode and it will
always triggers an error, there is apparently no way to get
the QFileSystemWatcher emit a signal when new files are closed
flusehd and not when they are just created.
Previously grids would always take precedence when both a grid
and guide were within tolerance of a point.
Now, guides will always take precedence - since they have been
manually set by users we make the assumption that they have
been explicitly placed at highly desirable snapping locations,
and should be selected over the general grid.
Additionally, grid snapping was previously only done if BOTH
x and y could be snapped to the grid. We now snap to the nearest
grid line for x/y separately. This means if a point is close
to a vertical grid line but not a horizontal one it will still
snap to that nearby vertical grid line.
