fix Bring to Front/Send to Back by putting them in the popup menu. It would be better if the user could select multiple objects at a time, but the x/y coord-based implementation doesn't allow for that.

for legacy drawing commands like [filledpolygon], don't scale the stroke (this is how it worked in Pd Vanilla)

* add flag for compatibility with older OSX versions
* change library paths in script so that external dependencies are found
* build with jack support

fix regression where glist_select can send messages to the GUI before the window or its elements actually exist. (Same thing happens in Vanilla, but tcl/tk silently ignores tk canvas itemconfigure messages for non-existent objects)

fix #114: can't copy-paste ASCII character 160, non-breaking space. Now we only remove consecutive \u0020, and leave the non-breaking spaces alone

fix #119: store canvas title for later use. This will properly display the title for a dirty canvas in the case where the Pd patch is mutated with a loadbang (and properly other cases, too)

fix a crasher with gtemplate_new dereferencing a freed pointer, and harden rule for creating a struct

Remove kludge for menu popup position. As of nw.js v.0.16.1, it appears that the popup menu behaves correctly with zooming and scaling

These happen in Pd-Vanilla and Pd-l2ork, too. They happen when an iemgui is inside
a gop window and outside of the gop rectangle area-- Pd still forwards gui
messages for them.
