Missing selection rectangle with legacy data structure drawings

Vanilla draws a blue selection rectangle around selected scalars. E.g., see the screenshot below from the 4.data.structure/07.sequencer.pd example:

The selection rectangle is missing with purr-data:

This makes it very hard to work with "legacy" scalars in Purr-Data since you can never be sure which scalars are selected in edit mode.

The selection rectangle is shown (in orange) if scalars are rendered using the new svg drawing drawing commands ( 4.data.structures/pd-l2ork/ds-tutorials/08.circle.pd example):

This is on Linux using HEAD, but it's the same using beta4 on OSX 10.10.
