make [draw] arguments more closely follow the svg spec
* [draw circle 20 1 2]: radius=20, xcenter=1, ycenter=2
* [draw rect 5 10 20 40]: width=5, height=10, xoffset=20, yoffset=40
* [draw ellipse 5 10 20 40]: xradius=5, yradius=10, xcenter=20, ycenter=40

got scopehandle clicks working... now need to port scopehandle motion by adding a wrapper in canvas_motion of g_editor.c for Scope~

just use "default" pointer icon for runtime "clickable" items to disambiguate the editmode icon

use standard OSX keybinding for prefs

These are needed to fetch ASIO SDK and nw.js binaries

still need to deal with the extra lines from drawfg_mono
looks like we can just use redrawmono and get rid of drawfg_mono
