[Bf-taskforce25] View 2D API - Proposal

[Ton Roosendaal]

Hi,

I reviewed it in irc with Joshua. Doc looks good, had many open issues 
but I think Joshua can solve most now. :) He'll update doc soon.

Some noteworthy conclusions:

- sliders belong to view2d, don't get own region. Need nice design 
proposal for drawing and optional extra handles (zoom).
- view2d storage goes to region level.
- channel lists, but also button lists/windows, require own region + 
view2d.
- area-manager can handle internal view2d alignment (via 
notifiers/listeners), so you can keep a channel list aligned with other 
2d views.
- regions can add listeners to screen for inter-area alignment with 
specific properties (like visible time frame).
- view2d gets own keymap, with standard (UI-wide) keymap, to unify 
hotkey/mouse/device usage. Could look at optional overrides or config 
hints for it though.
- panels - if its height is limited, or internal display unlimited - 
can get view2d too
