Match Windows font metrics on Linux.

Match Windows font metrics on Linux.

With this change, many layout tests involving text match render trees
exactly. By turning off anti-aliasing we also almost match pixel
exact. There are a couple of single-pixel differences between Win32 font
rendering and FreeType however (see the bottom left pixel of an 'a'
glyph for example), so we aren't quite pixel-for-pixel yet.

Mike Reed expects to redo much of the font configuration code in Skia to
cope with complex text and subpixel text so, for now, I'm not going to
have anti-aliasing be a command line flag etc.
