The index of the tree column will not change while painting.
Neither will the number of columsn. So avoid a whole bunch of virtual
function calls by caching these two values at the start of painting.
This adds an implementation for the Home, End, Page Up and Page Down
cursor movements for TreeView.
Also, the Up and Down movement implementations are replaced by a more
efficient traversal mechanism: whereas the old code would walk over all
visible nodes every time, the new code only evaluates relevant sibling
and parent indices.

I hereby declare these to be full nouns that we don't split,
neither by space, nor by underscore:
- Breadcrumbbar
- Coolbar
- Menubar
- Progressbar
- Scrollbar
- Statusbar
- Taskbar
- Toolbar
This patch makes everything consistent by replacing every other variant
of these with the proper one. :^)
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
Fixes hidable horizontal scrollbars remaining visible even after
collapsing their responsible nodes. Tree column width defaults to
column header width if wider than current content.
