Original Redmine Issue: 21280

Redmine category:expressions

QGIS provides x_min, x_max as well as y_min and y_max functions to extract those coordinates from a geometry (particularly, lines and polygons).
It could be nice to have a way to also easily extract z min and max coordinates from geometries, without resorting to processing and aggregates expressions.

Also there is missing m_max and m_min. Please update title as this problem is almost the same.
