Encapsulate the conditional transformation and its error handling.
Depend on the presence of a transformation, not of a SRS.
This includes the behavioural change of not providing clipping when
the layer's SRS cannot be handled.
This is a behavioural change, but it is hidden by the fact that
Mapper fails to save the CS choice "Map" (GH-1768).
Choose the MapCoord builder function during construction.
If a feature does not have a SRS, we must reset the transformation
instead of using the one which happened to be created before.
Adds API which e.g. allows to use "WGS 84 (G1762)"
when GDAL would only offer "WGS 84".
Task: GH-1264 (NAD83 vs. WGS84)
