This tweaks the ordering of some struct members in some of the more
important structs so that the compiler won't insert wasted padding to
avoid breaking the alignment. Some members that were previously
unsigned long have been changed to unsigned int. These members need to
be able to fit in 32-bits to run on 32-bit machines anyway so there's
no point in having them extend to 64-bit on 64-bit machines. This
doesn't affect the public API.

We have found several times now when writing code using Cogl that it
would really help if Cogl's matrix stack api was public as a utility
api. In Rig for example we want to avoid redundant arithmetic when
deriving the matrices of entities used to render and we aren't able
to simply use the framebuffer's matrix stack to achieve this. Also when
implementing cairo-cogl we found that it would be really useful if we
could have a matrix stack utility api.
