fixed regression from IOhannes' proposed fix (see e7acc479 commit) that affects propagation of scalar pointers through the trigger object. Use scalar-help.pd to test.

implemented improvement for empty lists as suggested by IOhannes http://lists.puredata.info/pipermail/pd-list/2013-02/101518.html

improved logic for freeing rtext that alleviates memory leak but also does not crash abstractions and gop objects (there are still memory leaks apparent in l2ork_output~ external which may be linked to individual objects having incomplete free functions). See http://sourceforge.net/tracker/?func=detail&aid=3605235&group_id=55736&atid=478070 for more info

fixed memory leak (see https://sourceforge.net/tracker/?func=detail&aid=3605235&group_id=55736&atid=478070)

further refinements to the zoom algorithm involving gop subpatchers and their required opening when zooming to ensure proper displacement of components (abstractions are unaffected)

improved/sped-up gop redrawing when using non-accelerated objects, fixed glitching when the two are mixed, improved zoom feature when using embedded patchers (since they share the same font size)

re-enabled Miller's proposed fix (still in testing stages as it did not exhibit itself as a problem beforehand)

bug fix/improvement of select object (http://sourceforge.net/tracker/?func=detail&aid=3605240&group_id=55736&atid=478072)

reverted Miller's proposed patch as it suggests sluggish gui regression based on last 2 L2Ork rehearsals

added Jonathan Wilkes' canvasinfo and pdinfo externals (see http://osdir.com/ml/multimedia.puredata.devel/2007-10/msg00136.html)
