And remove some useless argument names. This is just preparation for the next
patch and shouldn't change behavior.

We basically use a couple primitives to draw these
(PaintRoundedRectWithRadius, FillRect), so making the code a bit generic
implementing stuff with WebRender seems straight-forward.

I've kept using the fallback codepath for the bits that draw complex
paths like arrows and such, but the rest of the things should work with
this patch.

A thing I'm not too happy about is the scrollbar painting setup (requires a lot
of boilerplate), but modulo template hacks make nsNativeBasicTheme a template
that receives its super class as a parameter or something) it seems hard to do
better.

Depends on D105930

I'm not sure I'll get to the reviews tonight, but even if Markus does, please hold off on landing this until we enabled the non-native theme on macOS in bug 1690842. My plan is to land bug 1690842 and all dependent patches tomorrow when we switch to 88 in Nightly. Thank you

We could land this with the pref off if you prefer.

Bug 1690842 just landed and appears to stick, so please feel free to land once reviewed. I was mostly concerned that this might introduce new test failures that would prevent bug 1690842 from landing, but I don't think we need to pref this off if the tree is green. I will also defer to Markus on the review here since he has already taken a first pass. Thanks again!

The only thing missing now are things that draw arrows / checkmarks.

Make the disabled range thumb opaque, to avoid dealing with clipping
(also matches all other browsers, fwiw).

So I don't know why yesterday's try run was green, but I can repro those failures with webrender disabled.

Markus, I think the overflow rect for the range is not accounting for the shadow offset:

OverflowRect: (x=4, y=4, w=172, h=32)
ThumbRect: (x=115, y=10, w=20, h=20), Inflation: (6 x 6), ShadowRect: (x=109, y=6, w=32, h=32)

(the thumb shadow rect is clearly going outside the overflow rect)

Fine to just do something like this? The cliprect changes are not really needed but no reason we need to clip to a bigger clip than necessary. I think that should also properly fix bug 1693346.
