Summary: Clipper should preview the result of the clip operation
Product: GtkRadiant
Version: 1.5
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: editor
AssignedTo: ttimo@idsoftware.com

In 1.5, the brush module does not support rendering the region-to-be-clipped.
This was removed for performance reasons, and should be reinstated in an
improved way.
The previous implementation would copy the selected brushes and re-compute
their intersection with the clipper plane every time a gl view was updated. It
would be simple to optimise this by using a callback to trigger updates only
when the clipper plane changes. Another optimisation would be to draw only the
polygons resulting from intersection of each brush with the clipper plane - one
polygon per brush.
