change type of scalehandle_new and h_master. Document some structs in g_all_guis.h and change some field sizes.

*tried adding scalehandle_free to the canvas_free class but is currently commented out until we figure out why is this causing a segfault...

*cosmetic fixes to g_canvas.c

remove canvas/glist arg in a bunch of recently added iemgui functions, and introduce iemgui_draw_move & iemgui_draw_config

*fixed handle behavior on iemguis (current implementation is not equipped to deal with config kind of actions, and it does not have to)
*streamlined GOP handles since now draw_select deals with explicit delete before redraw

big refactoring #11 : replaced %lxOBJ by x%lx and removed nlet_tag from all iemgui, among other smaller changes

*ported fixes for crasher when sending a "dsp" message to tilde objects.  Backported from Pd Vanilla commits [8019b5] and [5769c5]

*fixed bug where patch titlebars were not properly re-titled after using save-as function (possibly other file I/O operations as well)

*improved draw sprite so that it works within a group

*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)

- nested plots display properly
- plot is vis'd and unvis'd properly when deleting plot or struct
- commented out ugly plot_displace hack-- multiple plots should work just fine
- separated out garray dependencies into class "old_plot".  This way the changes I made don't affect garrays.  _Very_ ugly hack, but it was pretty simple to implement and will be easy to remove later.
- no crashes when non-existent arrays are entered into a [struct] that has scalars hanging around
- template_cancreate ported from 0.45
- added a function to get the offending struct (to use with "Find last error").  Not using it yet, though.
+ For creating scalars using an object box:
- scalar must have initial "float x float y" fields, in that order.  This means you can't accidentally type the name of the hidden garray structs and create a scalar.  (Nor any other structs that only have a "y" field, etc.)
- broken object box returned if the struct has a bogus array template.  (Although currently I'm just refusing to create such a struct.)

*updated latest additions by Jonathan--still need following fixes:
1) enter-leave demos don't work at all (any demo involving enter-leave)
2) crasher in easing is still valid
3) spin-spin-spin crashes pd-l2ork when trying to close the patch while the image is spinning and being animated
4) curve-bbox is still having accuracy issues (tkpath issue)
5) polar clock still exhibits issues of warping curve (tkpath issue)
6) On the 15.events.pd change call is never issued--is this another side-effect of me not applying everything?
7) Is there a 14. patch for ds-tutorials? I didn't find one.
8) in ds-tutorials is gmon.out necessary or is this a stale file?

*fixed bug where with JOC enabled in subpatch this only works for the bbox of the array, not the entire window
*made intelligent offset to various forms of array representations so that scrubbing with mouse accurately applies to closest points
*disabled drawing of a GOP rectangle inside GOP array window
*disabled ability to insert objects inside a subpatch with an array

added Jonathan's revision of the array properties and options with fixed font sizes and other minor fixes. LINGERING PROBLEM: array does not redraw (only after apply does it re-appear). Likely shouldvis problem.

*forced array graphs to keep GOP/hidetext under all circumstances (later update properties window so that the GUI reflects this rather than printing info in the console)

*forced hidetext on all gop arrays to make its resizing sane. Later update properties to reflect lack of this option.

backported comment resize marker, updated it to support pd-l2ork and selection colors, added fix to the resizable objects to support abstractions and subcanvases.

added forward mess patch by Jonathan Wilkes that enhances in-patch interaction (think: prancing ponies patch demo)

*gop leaving stale vanila objects
*fixed bug where closing subpatcher of gop patch/abstraction redundantly opens gop patcher/abstraction
*fixed bug where reordering did not properly deselect previously arranged elements

first stab at porting core GUI to tkpath with SVG goodness. new scrollbars that will hopefully put an end to the old painful scrollbar nonsense. pdtk_tip clean-up and improvements. tons of other small bug fixes. a number of issues/wishlists still exist before the next big release:
*improve g_array lower/raise to use new functionality (BUG! doesn't match any items)
*scalar is drawn behind at first
*Scope~ window name "h16ffd10" already exists in parent (likely resize hook)
	*Change appearance of the resize hook
*better getrect for scalars inside plot?
*reenable bgerror and t_tkcmd catch
*Clean-up and merge cyclone documentation

*fixed axes get inverted when going beyond the allowed range
*fixed min size based on nlets when text shown
