In theory we could test this change by writing a pixel test. I'm unclear of the value of adding such a test given that the build.webkit.org tester do not run pixel tests :(

> Source/WebCore/rendering/RenderThemeMac.mm:1617
> +    Page *page = o.document().page();

Nit: The * should be on the left:

Page* page = o.document().page();

> Source/WebCore/rendering/RenderThemeMac.mm:1618
> +    float pageScaleFactor = page->pageScaleFactor();

This variable is referenced exactly once in this function (line 1621) and its name does not add anything that cannot be inferred from its right hand side expression. I suggest that we remove this variable and inline its value on line 1621.

> Source/WebCore/rendering/RenderThemeMac.mm:1619
> +    float deviceScaleFactor = page->deviceScaleFactor();

By a similar argument, I suggest that we remove this variable and inline its value into line 1623.

On another note, this code is almost identical to the code that you added to RenderThemeMac::paintMenuList() in the patch for bug #147868. Can we share more code?

[Wenson Hsieh]

Good point. I'll pull both pieces of drawing code (search fields and selects) out to a common function in RenderThemeMac.

Thank you for iterating on the patch.

Nit: Missing period at the end of this sentence.

It's not necessary to use the .0f suffix as per the WebKit Code Style guidelines.

> +    if (ThemeMac::drawCellOrFocusRingWithViewIntoContext(cell, paintInfo.context, rect, documentViewFor(renderer), shouldDrawCell, shouldDrawFocusRing, shouldUseImageBuffer, page->deviceScaleFactor()))

I know this is not part of your patch. I noticed that ThemeMac::drawCellOrFocusRingWithViewIntoContext() takes its first argument as a RetainPtr. Can we have it take a raw pointer?
