chrome/grit/theme_resources.h ?

[Reilly Grant (use Gerrit), 2015/10/30 22:33:15]

I guess something is putting chrome in the include path? There are a lot of
instances of #include "grit/..." in the tree even though there is no toplevel
grit directory.

This is generated file.

I believe grit/theme_resources.h is old way and works for compatibility reason.
new code should use chrome/grit/theme_resources.h

Yes, there's a bug to fix all the grit/ ones, but I lost interest. May get back
to one some day.
