1624514 - Provide a convenient API to get a frame's logical content size

Status: RESOLVED FIXED

(Core :: Layout, task)

Description

[Ting-Yu Lin [:TYLin] (PST, UTC-8)]

We have at least two use cases [1] [2] that use GetContentRectRelativeToSelf().Size() and then convert the physical size to logical size. We can provide an API for this.

Attachment: Bug 1624514 Part 1 - Move nsIFrame's methods that get various frame rects closer to GetRect(). r?dholbert

Let's make these methods more coherent and discoverable by moving them
closer to GetRect().

Attachment: Bug 1624514 Part 2 - Generalize nsIFrame::ContentBSize() to be ContentSize(). r?dholbert

To get the logical content size of a frame, some callers use
GetContentRectRelativeToSelf().Size() and then convert it to
LogicalRect. We really should generalize ContentBSize(), and provide
ContentSize() for such purpose.

Depends on D68064

These changes look sane to me (I gave them a quick skim and nothing jumped out at me).

Perhaps we could have AlaskanEmily pick these reviews up, though?

Sure. I'll redirect the review to Emily.
