scroll test failures on FF3/mac

[bill]

I'm seeing the following failures on FF3/mac when running the scroll tests through tests/runtests.html:

     _AssertFailure: http://localhost/trunk2/dojo/_base/_loader/bootstrap.js:538 doh._AssertFailure: assertEqual() failed:

Looks like the same errors also appear when running test_scroll.html directly.

This is with firebug enabled (not sure if that's connected).

Tests are running correctly on FF3/windows.

Verified FF3.0.6 on Windows works, on Mac doesn't. That's not supposed to happen, to my knowledge.

(In [16687]) Fixes #8633 !strict. Allow for scrollbar of any size (fractions of a pixel in FF with max zoom up to 34 pixels with min zoom). Adjust test to work with different scrollbar sizes. Note that test_scroll.html currently only reports correct pixel values for unzoomed env.
