Allows raster pixels to be labeled with the value taken from a raster
band.
Labels are registered with the labeling engine, so participate in
label conflict resolution and overlap avoidance
Options include
- Selection of band to take values from
- Using QgsNumericFormat to customise the number format for the labels
- Uses text renderer, so supports buffers, shadows, etc
- Label priority
- Scale dependant visibility
- Optional pixel size dependent visibilty, ie show only when pixels are
> 4mm in size
- Z index control, overlap avoidance mode
Fixes#14408
Because some method (only QgsGeometry::set actually) can be deprecated
only in python, not in C++. But \deprecated triggers the need for Q_DECL_DEPRECATED
This brings to renderer for Mesh Contours option to set renderer Min Max based on extent (specific canvas, changing canvas) in the same way as renderers for Raster Layer.
Allows easy retrieval of the geometry column name from the data
provider, if applicable.
(This was NOT possible to retrieve in a consistent, provider
independant way before)

Allows raster iterator to calculate blocks which are exactly
multiples of the resampling factor, to aid in cases where the
iterator will be used to fetch resampled raster blocks
Double-clicking a handle will auto-size the label to exactly fit
the contained text (growing or shrinking as needed). The opposite
side of the label will remaining fixed in place, so eg double-click
the bottom-right handle causes the bottom-right corner of the label
to move.
This is similar to what is achieved in
`QgsRasterLayer::refreshRenderer()` to refresh the renderer according
to an extent. Contrary to the first one, this method does not perform
any GUI update or emit any signal.
It is not used at the moment. This will replace the logic to refresh a
renderer in the following commits.
