make sure threadsafe rasterization ops are efficient

closes #1032

[rafaqz]

Suggested change

	const COMMUTATIVE_OPS = Union{
	const CommutativeOps = Union{

Actually a type not a constant

[rafaqz]

Suggested change

	_is_op_threadsafe(::COMMUTATIVE_OPS) = true
	_is_op_threadsafe(::CommutativeOps) = true

I really have no clue what is going on in the Documentation build. Seems to be some git issue?

[asinghvi17]

No, there is some problem in an example block, but it doesn't tell me which example block for some reason. Very weird - normally it does.

it is a link (asset) that is not downloading. We definitely need an independent source for these kind of assets. Basically, any USA based related link is a gamble.

[rafaqz]

Got a link to where that is? I can only see logging related errors

ahh no, sorry this is the issue ( ? is a Makie issue) @asinghvi17 ?

I thought we commented that out?

[asinghvi17]

But that can just get deleted probably and maybe if someone can file an issue about that, I can get around to looking at it soonish

[tiemvanderdeure]

Ah if it's still that issue I made a PR to makie to fix it: MakieOrg/Makie.jl#5327

[tiemvanderdeure]

I think we can merge this? The documentation issue will be fixed whenever the Makie folks bump ComputePipeline
