af0d68b882 Implement QgsGeometry::isEmpty() 
Faster than QgsGeometry::isGeosEmpty() because it avoids the
conversion to GEOS geometries and just uses the QgsAbstractGeometry
subclasses directly.

Also implements faster isEmpty() overrides for specific
QgsAbstractGeometry subclasses.

49432a8468 Optimise QgsAbstractGeometry 
Make nCoordinates virtual, and provide shortcuts for some
geometry types. The base method which calls coordinateSequence()
is quite slow in certain circumstances.

Speeds up rendering point layers by ~25%, also likely to
speed up lots of geometry heavy operations throughout QGIS
