add gui_x for sending hex value inside an array to the gui. Not sure if this is really necessary, but it makes it easy to send a list of open windows for one of the extant interfaces

Death to tcl Part 1 (cont.): remove old uncommented code and sys_vgui calls that are replaced by gui_vmess

Death to tcl Part 1: remove all sys_vgui messages that match the following constraints: 1) code is not annotated; 2) has a corresponding gui_vmess replacement; or 3) old commented code that is obviously no longer needed

fix regression with [pd] not respecting new box dimensions when renaming to [pd foo]. Also, comment out more sys_vgui calls in g_canvas.c

add workaround for out-of-order request from Pd that tries to destory a border on a scalar it already told us to erase

first try at get the copyfromexternalbuffer logic ported. This allows to paste Pd source code into a patch

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

update open dialog window height/width/font/fontsize for iemguis as they are resized/repositioned with the mouse

disable canvas menu options when the dialog is present. Also, change variable name "o" to something less error-prone

Give window focus when asking if we need to save before closing. Using a (possibly buggy) "restore" method instead of the more obvious "focus" method, so this needs more testing

fix iemguis and canvas scalehandle to track mouse position instead of delta-- this fixes a bug when the mouse goes below the minimum dimensions. Plus, some more cleanup of the scalehandle code

restore the ability to show multiple iemgui label handles at once, and use class instead of id to identify them
