2008-05-18 Martin Nordholts <martinn@svn.gnome.org> Merged the Polygon Select Tool capabilities with the Free Select Tool. Among the things still to do is improved help texts, more suitable graphics, and cursor mangement, but the core functionality is in place. Thanks to Alexia Death for initial testing. It will also be neccesary to do some work to adapt the Foreground Select Tool to the new Free Select Tool implementation. Quick instructions on how the tool works: o A click adds a polygonal segment, a drag adds a free-hand segment o Return-key commits, Escape-key cancels, Backspace-key removes last segment o You can grab and move segment vertices o You can cancel both a move, and the creation of a segment * app/tools/gimpfreeselecttool.[ch]: More or less reimplemented. We keep a sequential array of all the points in the polygon (including the free segments), and we have another array with point indices that we use to represent the segments. On top of this we have a few helper functions that tries to abstract away the pretty raw nature of the implementation. * app/tools/gimpforegroundselecttool.[ch]: Keep track on its own last_coord, and adjust to the new implementation of the Free Select Tool. Still needs some work, for example handling that the Free Select Tool now resets GimpTool::display. (gimp_foreground_select_tool_key_press): Pass on key event to parent class when appropriate. (Bails out too early though...) svn path=/trunk/; revision=25693
