[Qgis-developer] QgsMapRenderer and QgsMapSettings relation

[Sandro Santilli]

I've found code dealing with aspect-ratio adjustments in two places:
QgsMapSettings::updateDerived() and QgsMapRenderer::adjustExtentToSize()

As I'm trying to deal with viewport rotation, any such duplication makes
the work harder as things need to be changed in many different places.

Similar thing happens for QgsMapRenderer::setExtent, which is also
present in QgsMapSettings.

As QgsMapRenderer is actually initialized with a QgsMapSetting object,
should it always use services exposed by that class rather than re-doing
things locally ? Or what am I missing ?

Thanks in advance.
