comment out some sys_vgui calls which are _probably_ no longer necessary (plus extra comments saying as much)

further refined legacy mode to match both iemgui and graph-on-parent objects.

 *added legacy option for iemgui objects. Starting pd-l2ork with -lega…

…cy flag positions iemgui objects in their old, vertically inconsistent locations for the sake of retaining complete backwards compatibility.

*added sys_legacy global for inclusion of other potential legacy breakages that may develop later.

fix feature for putting array in existing graph
add a delete checkbox for graphs with multiple arrays

*added legacy behavior for key* family of objects where autorepeat is observed (just create an object with an optional argument of 1)
*fixed bug where gatom after pressing return should not stay focused
*fixed bug where gatom's number after ctrl+click should not turn selected
*offered ability for image and others to ignore clicks and pass them below (measured by a zero width, only works for single inlet/outlet objects as otherwise their multiple inlets or outlets will be truncated to the same spot)
*reenabled ability for cnv to pass clicks below and reflected this in the official help file (separate previous commit)

*reverted commit 46933bb2 as it deemed unnecessary (it was designed to support buggy backwards-compatible behavior that defies common UI practices).
*further enhanced getrect calculation for the mycanvas widget to disallow clicking through a canvas across its entire size, rather than just the area by which one can "grab" and move the widget

*fixed regression where cnv objects captured runtime clicks due to pd-l2ork's passing of the click to the topmost visible object, rather than the first clickable object in the stack. This also fixes problems with legacy patches that rely vanilla/extended's assignment of click to the lowest, and as is the case with s-env-help.pd in s-abstractions, invisible object, rather than the one apparent to the user.

*fixed consistency check failed: glist_findrtext when enabling gop and dragging its size around with other text objects on the canvas
*refined checking of gop size due to its text not being hidden, including after saving it to file (from Untitled to something longer, for instance)

*fixed one stale leftover of redrawing the patchcords inside graph that did not conform to the new style of drawing cords

*added getscroll after redrawing gop and scalars that have been changed via properties dialog in case their xy positions changed

*improved fittograph for multiple arrays (still needs some work)

*further improvements on the garray selection and redraw--fixed garray contents not remaining selected after dialog properties have been applied
*still need to explore problems with multiple arrays in a single GOP

*fixed segfault when resizing array via dialog (regression from May commit). Still need to work on fittograph logic for situations where there are multiple arrays in the same GOP

suppress creation of drawcurve, drawnumber, drawsymbol and plot when the user tries to create them inside a group.  (Currently their click and motionfns don't take the parent transformation matrix into account)

* suppress redraws for drawing commands if the group that contains them is getting deleted

*patch to add [group] data structure and supporting fixes (work in progress with lingering bug of being unable to display data structure arrays properly, see tiger.pd demo patch in data structures)

first step at cleaning up nested-gop bug (still need to work on scaling the objects to properly fit nested gop xy range)
