[cairo] Compilation errors with MSVC after recent changes to 'cairo-path-stroke-traps.c'

[John Emmas]

Hi guys.  Since updating form git master just now I can no longer 
compile cairo-path-stroke-traps.c with Microsoft VC8.  I see around a 
dozen errors looking like this:-

     cairo-path-stroke-traps.c(302) : error C2440: 'initializing' : 
cannot convert from 'cairo_point_t' to 'cairo_fixed_t'

The stated line (302) seems to be newly added and looks like this:-

     cairo_point_t t[] = { in->point, *inpt, *outpt };

Similar errors are occurring at lines 303, 464 and 465.  MSVC seems to 
be objecting to the array elements for some reason.  I can't see an 
obvious problem but fortunately, all the newly added lines look quite 
similar (so hopefully that'll make it easy to fix!)  Thanks.
