removed selection from the undo queue as it precludes selecting older stuff and pasting it into new stuff (undo -> select old would purge the queue ahead of that undo, so -> redo -> paste would be impossible)

fixed automatic resizing of the gop when changing font sizes, complete overhaul of the tooltip engine. TODO: add proper nlet tags to iemgui objects...

added support for tooltips (based on the http://sourceforge.net/tracker/?func=detail&aid=2838176&group_id=55736&atid=478072)

by tag in which case gop will fall back to the old way of redrawing

fixed all iemgui objects to conform to the new model of gop selection (no highlighting of objects inside gop unless they are toplevel objects)

altered behavior of gop objects so that internal elements are not visibly selected. Also reworked the way array and scalar selection is dealt with fixing segfault and making a more fool-proof way of selecting them.

improved logic for moving gop objects by checking if the gop has any legacy objects inside it that don't support displacefnwtag

improved out of focus typing behavior by including focused window information to the canvas_key function

further refined calculating size of g_mycanvas (when inside GOP getrect returns full size, whereas when on the toplevel canvas, it returns only the selectable rectangle)

fixed recreation of abstraction after saving it in its own independent root instance due to stale canvas_undo call that is not being used any more.

made gop resize and move hooks visible only when nothing else is selected on that canvas to minimize possible overlap of selection hooks

fixed bug where gop element with hidden text still did not allow resizing below the width of the text

added ability to deselect currently selected objects from the canvas if focusing outside the said canvas window

added automatic focus of the root window at start-up and fixed copying text from the console window into the clipboard using ctrl+c shortcut

implemented free() calls as part of the pd_quit() call from the following sourceforge bugtracker: http://sourceforge.net/tracker/index.php?func=detail&aid=1502860&group_id=55736&atid=478072

fixed confirming saving changes on an abstraction hidden inside another patch (currently invisible) whose prompting failed...

made openpanel and savepanel open by default in the folder where the original patch was opened from.

Improved logic for intelligent asking when to save abstractions. No longer is it necessary to check whether to save an abstraction after it has been changes and only displaced on parent. this is because objects are "activated" when selected which potentially means that abstractions would be recreated as soon as they are deselected essentially making user lose anything they changed in the abstraction and did not save. However, in pd-l2ork we check when objects are activated whether their rtext (and therefore also its arguments) have changed and only recreate object if they did.

fixed three regressions that crept in due to implementation of moving gop objects by tag. one of them manifested itself when an object was altered as gop and a sub-patch pops up asking to discard changes made to it. upon returning on the main window with the said gop, due to redraw objects were not reselected so dragging the object would not redraw properly even though it could be displaced, resulting in a seemingly stale gop object (in actuality it was simply displaced by being dragged while its visual content did not displace). Also, excessive stdout errors regarding redrawing gop resize handles and possible menu edit update has been dealt with.

Fixed segfault when creating undo for array apply (e.g. when changing array size). Also expanded moving by tag to arrays and scalars. Now, the entire array even with a ton of points is moving like knife through the butter :-)

Added support for moving GOP objects via tag and disabled showing of resize handles on iemgui objects when displayed inside a gop window (this became an issue due to new way of selecting gop objects which now also includes all objects inside it).

finished implementation and debugging of infinite undo. removed debugging statements from stderr, vastly improved pasting from external script.

finished undo implementation, added consistency to how canvas properties window is handled in undo situations, removed debug output.

added comments that suggest UCUT_TEXT is now obsolete and replaced by a much better undo_recreate (action 10).

more improvements to the cut mechanism. implemented rename function (11th undo action proved unnecessary and is serviced by 10). improved logic of retexting objects so that only those that have changed trigger an undo snapshot.

removed rendundant memory hack and found potentially real and permanent fix to the double-entry bug (see g_canvas.c inside canvas_free() function). Many thanks to Krzysztof Czaja for his incredibly helpful hint!
