* Rudimentary scrolling shows a Left and Right button at the top of the
Doodad Palette if your window is deemed not tall enough to contain all
of the doodads.
* A "progress bar" is shown between the buttons indicating the
percentage of your scroll down the doodad list. When you're able to
see the final row of doodads, the progress bar is at 100%.
* Toolbar has icon buttons for the Pencil Tool, Line Tool, Rect Tool,
Actor Tool and Link Tool.
* Remove the tab buttons from the top of the Palette window. The palette
tab is now toggled between Swatches and Doodads by the tool selected
on the tool bar, instead of the tab buttons setting the tool.
* Remove the "Link Doodads" button from the Doodad Palette. The Link
Tool has its own dedicated toolbar button with the others.
