Hi,

this is a heads up for a large libgui patch I'm going to
checkin soon.  This doesn't actually touch any code that
Insight uses, but if you see any strange build problems with
libgui, it's probably my fault.

ChangeLog:
	* src/tkCanvEdge.c (CreateEdge, EdgeCoords, ConfigureEdge):
	Objectify functions to use Tcl_Obj instead of char**.

	* src/tkGraphCanvas.c: Cut and paste parts of the new
	Tcl8.3 tagsearch code in to replace old.  Rewrite much
	of the code to use the new tagsearch features.

I've sent the patch as an attachment on this email.

Ian.
