Bug 101949 – [Chromium] Refactor theme font lookup into a factory

• Component: Platform
• Status: RESOLVED FIXED

[Scott Violet]

Long term we would like to allow RenderThemeChromiumLinux to run on both windows and linux. However the font lookup should remain platform specific. We need to refactor font code out of RenderThemeChromiumSkia into platform specific methods.

R=me, but you need to fix up the style warnings.

Nit: It's not that common to prefix a method with 'get' in WebKit. Something like initializeSystemFont might be more descriptive.

These look like static initializers too, although MSVC won't complain about it.  Hmm, maybe make these pointers and initialize them lazily in systemFont()?

I was worried about call order, so I went with DEFINE_STATIC_LOCAL.
