[fireball] 44112: - Implement GetDC/ReleaseDC for window manager with clipping support. This addresses the invalid drawing order "bug", which is in fact a feature. Client window manager is responsible for compositing all windows in a given rectangle being redrawn. Arwinss implements a very simple client window manager (SWM) which just clips out all contents behind the window on top of a z order. - Notify SWM about a new (or an existing) desktop window. - Fix comment typos.

Log:
- Implement GetDC/ReleaseDC for window manager with clipping support. This addresses the
invalid drawing order "bug", which is in fact a feature. Client window manager
is responsible for compositing all windows in a given rectangle being redrawn. Arwinss
implements a very simple client window manager (SWM) which just clips out all contents
behind the window on top of a z order.
- Notify SWM about a new (or an existing) desktop window.
- Fix comment typos.
