+positions.
+
+Actually, this was added as part of the horizontal scrolling GSoC
+work. We need to investigate how costly this is.
+
+
+* Proposals
+
+** get rid of pm::insetDimension.
+
+The information contained there is already in bv::coordCache.
+
+Effect: only code simplification.
+
+** set inset position during metrics phase
+
+This implies to set inset positions relative to outer isnet during
+metrics phase and then in a second loop to descend into insets and
+update positions correctly.
+
+Effect: avoid going through the painter machinery when it is not necessary.
