[PD] <<Loaded>> event

[Jonathan Wilkes]

Hi Hans,
     I'm close to finishing a revision of my tooltips patch.  To properly loadbang a canvas tip 

I need something like a <<Loaded>> event, but one that tells me when the a pd patch window has 

finally finished being drawn by Tk.  <<Loaded>> seems to trigger once the procedure for creating 

a new canvas has finished (technically right before, I guess), but it doesn't tell me when Tk has 

actually finished drawing the window and setting all the window dimensions that are query-able 

through winfo.

I think I could use <Configure>, but it will trigger multiple times-- I just want one event that tells me 

"Ok, everything that needed to get drawn as a result of creating this patch window is done drawing."  

(tcl/tk wiki warns against "update idletasks" which can cause subtle bugs.)
