Changes in the layer API:
* The setDatasource() methods become non-virtual public method
* The virtual private setDataSourcePrivate() method is defined and the provider setDataSource implementations have been moved to this new virtual method
* Add missing headings and ToC anchors
Adds missing headings (and table of contents anchors) for 'Renamed Enum Values' and 'Renamed Methods' tables.
* Removed table captions
Which are redundant due to the headings that the tables sit under
This options is broken in QGIS 3.0, but in any case has been
mostly made redundant by the live styling dock, and the other
non blocking color pickers which are implemented in most areas
of qgis now.
Before we had two checks - equals() and isGeosEqual() which
performed the exact same check (since equals() called the geos
equality test)
Since the geos equality test is a slow, topological test, which
considers two geometries equal if their component edges overlap,
but disregards ordering of vertices this is not always what we
want. There's also the issue that geos cannot consider m values
when testing the geometries, so two geometries with different
m values would be reported equal.
So, now calling QgsGeometry::equals performs a very fast, strict
equality test where geometries are only equal if the have exactly
the same vertices, type, and order.
And swap most code which was calling the slow geos test to instead
use the fast strict native test.
This forces Python code and plugins to become datum transform
aware, and given that upgrading python code is easy (just
add QgsProject.instance() as a new argument to the constructor)
it's relatively painless to force this on PyQGIS users.
Also fix upgrade the easy QgsCoordinateTransform c++ constructors
where the project is available, or where using QgsProject::instance()
is safe to do.
For others, just avoid the deprecated warnings until we can
get access to the correct project instance where the transform
is being constructed.
These methods are not used in master and are of questionable
value. Better to serialise the source and dest crs separately
and create the transform when required
* update HTML data provider metadata for grass, gdal and ams
* update HTML data provider metadata for WMS and WCS
* move HTML bullet list to QgsHtmlUtils
