This should probably be: inflateListItem(RenderListItem*, RenderListMarker*);

[skobes, 2014/01/28 03:10:30]

Even if we don't need anything from those classes, and wouldn't otherwise need
to #include their headers?

[pdr., 2014/01/28 04:50:46]

Yes, type safety > compile time :)

There's no need to include the headers in FastTextAutosizer.h, just
forward-declare the classes like so:
class RenderBlock;
class RenderListItem;
class RenderListMarker;

You will need to include the RenderListItem and RenderListMarker headers in
FastTextAutosizer.cpp though.

Done.
