[Bf-committers] Resizable widgets

[Xavier Thomas]

Hi,
I was reading the "handling large lists" discussion and discovered some UI
issues that are not related to the length of the list but to the way
resizable widgets are handled.

-First issue is, almost nobody knows that lists widgets are resizable with
"Shift-Scrollwheel".
-Second issue is, other resizable widgets (histogram, waveform, vectorscope
and maybe other) uses other keybindings to resize/pan/zoom
-Third, the keymap for those operations are not editable in user prefs.

My idead would be quite simple: replace the "shift-scrollwhell" shortcut
for resizing lists and uses 2 "notch" under it to make it "dragable" like
histogram and waveform. In my opinion this communicate more the fact that
the widget is resizable,  would fix the first 2 issues and work around the
3rd.
