Slider: bump boundary tests indeterminate

[bill]

The a11yBoundaryTest and boundaryTest in Slider_a11y.html and Slider_mouse.html are indeterminate. I.E., they sometimes fail, due to a problem with the test.

Those two tests test the sliders to see that clicking the left/right button (or using the left/right arrow keys) moves the slider to it's min/max value. The first test, for example, sets the slider's value at 0.2 and then does a left arrow. This will move the slider to 0, unless the slider is very wide, in which case it will take two (or more) arrow clicks to move to zero. (NOTE: this fails on sliders where discreteValues is *not* specified.)

test_Slider.html defines the width of the first slider as style="width: 50%" which exacerbates the problem since it's different depending on your browser window. But, you can reproduce the problem by setting style="width: 764px".

A further complication is that setting style="width: 764px" means that the number of possible positions of the handle is less than 764, due to the width of the button nodes and margin/borders/etc.

So, ideally we should have tests for left and right arrow on sliders when discreteValues is not set, but it's hard to write them.

(In [17025]) Make slider1 narrower to avoid test failures on wide browser window. We still don't have a good test though for when discreteValues is *not* specified (i.e a test to make sure that the arrow keys move up/down 1 pixel), so leaving ticket open. Refs #8884.

Fixes #8884. Fix no-discrete value tests to work with varying slider sizes.

Starting with [26732] I'm getting a failure in Spinner_mouse.html on FF5/windows:

Fixes #8884. Firefox's fractional pixel values was playing havoc with Slider value calculations with very specific (unlucky) widget domNode sizes.
