[GFC] Extract hasStretchedBlockSize and stretchedBlockSize helpers in
GridLayoutUtils
https://bugs.webkit.org/show_bug.cgi?id=317885
rdar://180664653
Reviewed by Brandon Stewart.
Pull the block-axis stretch-fit computation out of usedBlockSizeForGridItem into
two standalone helpers. This is a behavior-preserving refactor that lets the
stretched block size be queried on its own, separately from the full
used-block-size logic.
hasStretchedBlockSize() captures the condition under which a grid item is sized
as align-self: stretch in the block axis (auto preferred size, normal alignment,
not replaced, no preferred aspect ratio, and non-auto margins).
stretchedBlockSize()
computes the stretch-fit size exactly as the previous inline code did: the row
size minus margins and border/padding, clamped by the item's max size.
usedBlockSizeForGridItem() now calls these helpers instead of open-coding the
computation.
* Source/WebCore/layout/formattingContexts/grid/GridLayoutUtils.cpp:
(WebCore::Layout::GridLayoutUtils::hasStretchedBlockSize): Added.
(WebCore::Layout::GridLayoutUtils::stretchedBlockSize): Added.
(WebCore::Layout::GridLayoutUtils::usedBlockSizeForGridItem): Use the new
helpers.
