Hi Benjamin,

currently there isn't support for Z coordinates - as our class
QgsPoint doesn't include support for Z coordinate. However we aim to
implement proposed changes by the following RFC:
http://wiki.qgis.org/qgiswiki/GeometryHandlingRfc
Then, QGIS kernel will be more or less prepared for 3D data handling
(once also providers get updated to load Z coordinate).

Regards,
Martin
