border.html + style.css test case for CSS background

The last word in each line, encased in a tag with either a background or border value, is sometimes cropped in all Safari versions.

Firefox renderes the attached case in an expected manner.
Safari 5.0.2, Webkit 5.0.2 (6533.18.5, r68204), Webkit on the iPad iOS 3.1.2, and Webkit on the iPhone 3G iOS 3.1.2 are showing this unexpected rendering.

Proposed Patch

The WebKit project requires test cases to be landed along with bug fixes. This code change looks good, but we need either a test case or an explanation of why we can’t test it.

Patch

Added a pixel layout test ... LayoutTests/fast/borders/border-rightEdge-bug46632.html. 
The rightEdge of First2 element displays correctly with this fix. 

Modified the patch. Passing the endObject as an argument to 
the method determineSpacingForFlowBoxes directly without testing 
for end.pos.

Test case looks good. I'm not 100% certain the logic here is right because it’s slightly outside my area of expertise, but I’ll say r=me.

Patch

Created a new base line for test case css2.1/t090501-c414-flt-ln-02-d.html. 
The borders for the small boxes A.B,D are not displayed in full. The right edges 
are cropped. With this fix they would be displayed fully. Updated the png and 
checksum files for mac platform.

Patch

This patch doesn't apply cleanly anymore. But also, I think the bug has been fixed! The test case looks right in TOT, and the call to constructLine() seems to have a similar fix in place.

Resolving for now since I believe this is now fixed. Please re-open if it's not.
