More TODOs and future plans. Also finally removed the TODO about incorrect Area redraw on Windows.
More TODO/future plan shuffling.
Pinned down horizontal scrollbar behavior on Listboxes; also reworded the Area scrollbar behavior sentence a bit to match. Now to actually implement the changes...
Added horizontal scrollbars to Listboxes on Windows. Also fixed typos and bugs in Windows sysData.selectedTexts().
More shuffling of TODOs and future plans.
Consolidated NSScrollView code on Mac OS X to be all in one place.
Rolled back the Windows horizontally scrolling Listbox changes because I can't seem to get it to work on Mac OS X (and keeping that code there is inefficient); removed the guarantee of horizontal scrollbars in Listbox and made that a future plan. Both the Windows and the non-working Mac OS X code is in unmigrated/hscrolllistbox.go (and the unmigrated/ folder will be renamed shortly).
Removed unmigrated/main_windows.go; that test program has long since been unneeded.
Migrated cursors_windows.go and icons_windows.go.
Renamed unmigrated/ to experiments/ as I have now migrated everything and that folder now contains experimental code.
Removed winbuttonsize/; we're not going to use that for a while (the sizing we have now is fine; not optimal, but it works, for the most part). (We can always pull it back later.)
