*partial backport of a fix to allow subpatches to be renamed with no arguments without losing their inner content (see g_text setto call). Thanks to Jonathan Wilkes for the bug report.

*improved comment resize bar (made it into a dashed box)
*improved invalid object outline (box) into a dashed box and made such boxes solid when being edited to distinguish them from comments.

*restructured pdsend messages used by sys_gui object so that they are forward and backward compatible.

*fixed pd~ regression where instantiation within another instance of pd~ failed to start due to expectation of the new -unique flag without which all patches are opened within the existing instance.

- 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.)

code clean-up and enabling bunch of debugging to hunt down the infinite recursion in the scalar-help.pd (select the left object and observe your own aging process)

*cannot create two structs on the same canvas (otherwise how would you know which one you are talking to)?
*fixed regression where arbitrary font sizes were not honored by the drawsymbols and drawnumbers
*other minor clean-ups
*adjusted help file to reflect the new approach to font sizes

fixed findrtext consistency check error with 2+ level embedded gop scalars (may need further testing for regressions)

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

fixed scrolling algorithm for scalars, improved scrolling logic to avoid unnecessary updates, made scrollbars wider (easier to click) and less transparent
