Todd Volkert resolved PIVOT-71.
-------------------------------

    Resolution: Fixed

Fixed and verified no regression against Sun JRE.  With {1f, 1f}, you have to use CAP_BUTT as well to keep the ends from bleeding over into the gaps, and you have to turn anti-aliasing off.

> We've been using {0.0f, 2.0f} as our dash array for the skins that paint a dashed line to represent the focused state.  These values are incorrect, and we got lucky in that Sun's graphics runtime interpreted them the way they did.  The dash array {0.0f, 2.0f} means "repeatedly draw a dash of length 0.0f followed by a gap of 2.0f", which really means "don't draw anything"!  However, because Sun's runtime interprets a dash of length zero *at a non-zero thickness* to yield a pixel hit.  This interpretation is not shared by other JREs.  NOTE, what we were going for was a dash of length 1 followed by a gap of length 1, and {1.0f, 1.0f} yields the exact same behavior on the Sun JRE as we had before, but it also yields correct behavior in other JREs.  Thus, we should change all instances of the old dash arrays to the new.
