There was a previous fix for this protecting some geos calls, but
on newer GEOS versions we get crashes with other methods (eg
calculating centroid) when using geos geometries with empty
interior rings.
Avoid this by ALWAYS defaulting to skipping empty rings when
creating GEOS polygons, UNLESS explicitly asked to. Then, only
explicitly ask to do this when we are using GEOS to validate
a geometry. In all other cases we don't need or want empty rings.
For stable API use only, and then cleanup the private version
of this to remove all the consideration of 3.0 API compatibility.
Mark the archive copy as deprecated and remove in 4.0
This method has become completely unweildy because of all the
compatibility code. By making this private only we can rip
out all this old code and make the method much simpler and
easy to understand.
Before this commit, the stacked diagram properties were taken as a basis, losing valuable diagram settings in the process.

From the nmea specifications it is clear that the talker ID
does not have to start with 'G'. Accordingly remove ALL these
incorrect hardcoded checks against (a very small subset) of
known talker IDs, and permit any two-character string
as a valid talker ID
Fixes connection to NMEA devices which use "IN" for
talker ID (and others)
This adds two functions to setup clip planes on a 3d scene:
- enableClipping() to enable opengl clipping
- disableClipping() to disable opengl clipping
The `enableClipping()` function achieves 3 things:
- it stores the clipping plane equations
- it adds clip planes to the framegraph
- it enables the clipping on the material of the existing entities
`disableClipping()` does the opposite things.
The clip planes equations need to be stored to handle the dynamic
addition of new entities. Indeed, when a new entity is added, clipping
needs to be enabled on its material if necessary. This is achieved
in `finalizeNewEntity` which is called on all new entities.
However, this is not true for the terrain entity. That's why,
`mTerrain` now listens to the `newEntityCreated` signal to call
`handleClippingOnEntity()`.
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().
