Zoom Improvements
First, add a new "Zoom to Fit" toolbar action. This will look at the
size of the rendered image, as well as the size of the canvas area,
and compute the largest possible scale factor that will zoom the
rendered image while showing everything.
This is particularly useful when working with larger devices, such as
WXGA, where typically the rendering comes up showing only the top left
portion of the image, and the Zoom Out function often zooms out too
much since it does not have fine granularity.
Second, add icons to the various zooming functions. The zoom in/out
icons are from Eclipse WTP; the other three are minor derivations from
these icons (using = for emulate real size, 1 for 100% and an outline
for zoom to fit).
Third hook up zoom in, zoom out, zoom to 100% and zoom to fit to
keyboard shortcuts (applicable to the canvas only).
Finally, tweak some labels.
(Also updated the ddms screencapture icon, since there was a screen
capture icon in the same Eclipse WTP icon folder)
