This PR has a few merge conflicts.

I did a side by side comparison of the old docs and the new docs

Surface

• get_frect does not have a versionadded (in both versions) despite it being a relatively new method. Not the fault of this PR, just something I noticed.
• _pixels_address is documented before this PR, but this PR removes documentation for it. I think this is something to be fixed here.

Tranform

• pygame.transform.threshold has an example section before this, which is not in this PR. If this change was intentional, I think it is fine.

Good catch, forgot that private members need to be added to the rst explicitly. Fixed.

Yep, that is intentional. It was a test that was included anyway, I don't think that is a good example. But of course can be added back if others disagree.

I also combed through it, found a few things.

Surface.get_locks() return type looks strange
Surface.get_at() changes what previously seemed to be a note into a changed in 1.9 notice, drops a created in 1.9 notice.
image.load_basic has a line break between the 3rd and 4th sentence not in current docs

Surface.get_at() changes what previously seemed to be a note into a changed in 1.9 notice, drops a created in 1.9 notice.

I noticed that too, and assumed it's a fix made in this PR
