Bug 128631 – [CSS Shapes] shape-outside does not properly handle different writing modes

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Bem Jones-Bey]

ShapeOutsideInfo::updateDeltasForContainingBlockLine doesn't properly convert from the writing mode and coordinate space of the containing block to and from the coordinate space of the shape. Some of this is due to the confusing names of the variables involved, some is due to the fact that the logicalLeftOffset(), logicalTopOffset() and other methods in ShapeInfo use the writing mode of the float, not of the parent. This bug tracks fixing all of these issues.

I tried breaking this up into multiple patches, but had trouble coming up with tests for each piece.

I've gotta add a couple of ASSERT_NOT_REACHED to make EFL happy.

r=me with a rename suggestion.

> Source/WebCore/rendering/RenderBoxModelObject.h:121
> +    virtual LayoutUnit borderWidth() const { return borderLeft() + borderRight(); }
> +    virtual LayoutUnit borderHeight() const { return borderTop() + borderBottom(); }

I would suggest naming these horizontalBorderExtent and verticalBorderExtent. I dislike using terms like "width" since it could be confused with the actual border-width CSS name, i.e., a person new to this code would think the method was returning the pixel width of a single border.

I think renaming all of the other functions would be good too, i.e., marginWidth = horizontalMarginExtent, marginHeight = verticalMarginExtent, etc.

borderAndPaddingWidth could be horizontalBorderAndPaddingExtent, and then borderAndPaddingHeight could be verticalBorderAndPaddingExtent.

My ability to read error messages is apparently a problem. I need a return statement to shut that EFL compiler up!
