Description

Currently, it looks like one can use the map canvas attributes (id, rotation, center, height, width...) to style or label a layer.
However these variables are not available in areas like attribute table or selection tool: you may want to fill or format a field with value based on current map canvas property

See discussion at http://osgeo-org.1560.x6.nabble.com/Looking-for-a-function-or-variable-to-retrieve-canvas-extent-td5325029.html for a use case
