Formatting tweaks
https://bugs.webkit.org/show_bug.cgi?id=115427

Reviewed by Andreas Kling.

* platform/graphics/cg/GraphicsContext3DCG.cpp:
(WebCore::GraphicsContext3D::ImageExtractor::extractImage): Fixed indenting to match
normal WebKit style.

* platform/mac/ScrollAnimatorMac.mm:
(WebCore::ScrollAnimatorMac::pinnedInDirection): Removed an excess "+" that is harmless
but strange.

* platform/mac/SharedBufferMac.mm: Tweaked blank lines for better paragraphing.
