Fix an unreported issue with WMS client ignoring the advertised tile
size from GetCapabilities (because the raster iterator always used
its own hardcoded default).
A new method was added to retrieve this information from data providers
only implemented for WMS at the moment.
The test has been reformatted for consistency with other core tests
by moving the implementation outside of the class. The actual change is
the addition of TestQgsWmsProvider::testMaxTileSize().

We had two different(!!!!) implementations for equality operator
for QgsPointXY, with different logic (one handled empty points,
the other didn't). This compiled only because one was not marked
as const. So we'd get a DIFFERENT equality check logic depending
on whether or not the first point was const... eeek!
Remove the duplicate one, mark the better one as const
Instead of always calculating the scale along the bottom of the
map, expose a choice of methods to the user (along bottom,
middle, top, or average of the three measurements)
For new scalebars, default to the average method, which better
handles the scenario where the scale at the top or bottom of
the map cannot be calculated (eg when the top/bottom of the map
falls just outside valid areas for the map's crs)
This fixes one of the most common scenarios which cause scale
bar widths to blow out to massive sizes

When the aggregate uses variables, we need to ensure that the
cache key correctly considers the current value of ALL those
variables. Otherwise we'll return incorrect results when
an expression is re-evaluated after changing the variable
value for the context.
Fixes use of aggregate function with @symbol_label in legends.
Fixes#58221
Reduces a lot of overhead when rendering non-buffered, non-shadowed
text. Cuts render time by ~50% in my testing.
Also introduces a "PreferText" render option, where we default
to using text painting methods in all scenarios where we know
there's no loss in rendering quality to do so. This mode should
become the new default in a future QGIS release, as it is
designed to be faster with no visible rendering differences.
Expand unit testing by covering all text render modes in all
text renderer rendering tests.
`QgsPolyhedralSurface` inherits from `QgsSurface` which implements
`QgsAbstractgeometry::isValid` by calling `isValid` from
GEOS. However, GEOS does not handle polyhedral surface. This means
that `isValid` will always return False even if the polyhedral surface
is valid.
This issue is fixed by implementing
`QgsPolyhedralSurface::isValid`. It checks that all the polygons of
the polyhedral surface are valid.
I limited the renaming to things that are not in the public API and
are not setting names. This is probably more than we strictly need to
do, but at least this will help doing potential future similar 'grep'
exercises.
And add to "Advanced Python field calculator" algorithm, as that
algorithm uses the Python exec() function and is a security
risk if run with untrusted/unchecked inputs
Allows use of img tags in HTML label content. The following logic
is applied:
- Image path is set via the src="xxx" attribute. Local, HTTP, and
base64 encoded paths are permitted
- Any image format readable by QGIS can be used
- Image sizes can be specified via the width="##" and height="##"
attributes. If width or height is not specified it will automatically
be calculated from the original image size
- If width or height are specified, they are considered to be
in POINTS
- The css width/height settings are NOT respected (this is a Qt
limitation)
- Images are not supported for curved text labels
- Images are placed inline only, floating images are not supported

Adds support for base64 encoded image decoding when the path
is a HTML data URL (in addition to the existing "base64:..."
format support)
Allows use of eg "data:image/jpeg;base64,XXXXXXXX" formats
for image paths, so that the image cache can correctly handle
embedded image paths from HTML/CSS content
* add template method to return specific type of layers in map canvas
* Apply suggestions from code review
