Update pixman to 0.19.2

Updates pixman & cairo to their current releases. This also exposes the cairo
option to disable some floating point math - since it is actually made use of
in this release.

Update pixman to 0.19.2, take 2

This is a slightly cleaner version of the pixman patch in that it updates the
no tests patch against the current version too.

Paul,

Could you give a few more details on why the new patch
cairo-1.10.0-packttstructs.patch is necessary ? The description at the top of
the patch doesn't really explain the why.

Thanks!

Sure, essentially if you look at src/cairo-truetype-subset.c lines 98-111, you
can see that the size of the structs must match the sum of the size of their
fields, ie. have no padding, because these structs are being read from font
files which obviously aren't padded to word boundaries on disk. At least with
the compiler I'm using that was not the case by default, but the packed
attribute ensures that padding isn't added and the checks pass.

This should probably be reported upstream, I'll get to that later today.

pixman is now at version 0.24.2 and cairo at version 1.10.2, so this bug can be
closed.
