rename WidgetPod::paint_with_offset to just 'paint'

[cmyr]

This has been a long-standing todo, and I think it makes sense; it's a bit of a gotcha right now.

What is currently 'paint' can get some other more annoying name.

What's the benefit of the current paint? Just performance when the origin matches? I'm thinking how often does it even get used and for what purpose.

For now I'm thinking perhaps something like the following:

Current name	New name
paint_with_offset	paint
paint_with_offset_always	paint_always
paint	paint_with_current_origin

[cmyr]

I think that paint might get called by the others, after applying the transform? I'm not 100% sure though. Those names look good, maybe paint_raw instead of paint_with_current_origin but just spitballing.

I will make a PR for this. As per discussion here's how I will rename things:

Current Name	New name
paint	paint_raw
paint_with_offset	paint
paint_with_offset_always	paint_always

Should we proceed with these renamings?

[xStrom]

Yeah I think those names are fine. Remember to also update documentation references where it makes sense.

[totsteps]

Once the paint_with_offset is renamed to paint there will be name conflict at line druid/src/core.rs:372 and 373.

Not sure how to resolve this!?

- their [`paint`] method.
+ [`Widget::paint`].
