[PD] Unnecessary scrollbars since 0.49

[Dan Wilcox]

Try this as a small test: add a new line with "return" after the "update idle tasks" on line 302 of tcl/pd_bindings.tcl.

This should force the window the create it's size, then ignore checking the scrollbar until the next scroll event. What might be happening is a delay between creating the window, creating some objects near the scroll edges, and/or the window resizing. Adding the return might try to avoid that the first time around which is what my older, more complicated fix did.

To see the change in an macOS .app bundle: close the app if it's running, right click on the app, and choose "Show package contents", then navigate to Contents/Resources/tcl, edit and save the file, run the app.

This is one of those things that I'm not really seeing too often on my system but, since it's related to timing of events, curl be happening on others if their timing is different.
