effective API/ABI surfaces

Just wondering about what sort of things are considered ABI breaks in reality,

>From my understanding, I should be able to

a) add new members to end of ScreenRec.

b) add new members to xf86ScrnInfoRec in the reserved sections.

Can I though add members to GC, Pixmap, Picture structs or does someone do
bad things with them?

Before we freeze the API/ABI I'd like to maybe expand some of these
structs if I can't do it later, so I can ship 1.13 but with some
features in it,
