nullptr, [](start = 50, length = 8)
you're not currently getting the descent though, so it doesn't look like this would've changed anything?

(i think ascent + leading would've been correct here in any case)

You're right, added a comment and reverted change

nit: I would probably just make the comment be about what the SetTextPosition is actually doing? "because CG origin is the opposite vertically from UIKit origin, flip the y line origin from upper left corner to lower left corner (baseline)", except use better wording than i did

-transform.c [](start = 78, length = 12)
i'd been wondering for a while why this was missing...

I'm not quite sure how it worked before

Good catch. Please add a page to CTCatalog for rotate. Also I'd like to start adding automated tests that validate the contents of bitmap context to catch regressions that would be easy to miss with untrained eye.

These files also need to be added to xcodeproject and should compile and run on reference platform.

Already done and tested

I would change this text to read what the expected test result should be (changing rotate should cause the text to rotate in which direction?).

left alignment here to easily see the pivot point?

nit: it'd be nice if the sliders had labels, but it's fine as-is

This colorspace does not seem to be used.
Fixes incorrect rotation introduced by my recent math changes and adds descent to nslayoutmanager line drawing to make exclusion zones more accurate
Fixes #1275
This change is
