Gio up

[sbinet]

Please take a look.

[sbinet]

this isn't the final answer: the new Gio API doesn't lend itself very nicely with our Push/Pop semantics.
see 1 for more details.

(but we don't use explicitly Push/Pop in the vg/vggio tests. I'd expect plot/plotter.Field.Plot to fail)

also, it seems the latest Gio version has a somewhat different kerning algorithm.

this needs https://lists.sr.ht/~eliasnaur/gio-patches/patches/40703

I haven't understood (yet?) why the embedded image is so blurry.

[sbinet]

I haven't understood the blur, but I know where it comes from:
https://lists.sr.ht/~eliasnaur/gio/%3CCS8BHEBZ9GR5.NAXSHL22P0UG%40clrinfopc42%3E#%3CCSBMYF60V5V2.38PUCTE2N4NPI@clrinfopc42%3E

[sbinet]

so the blur comes from a different filtering algorithm used deep inside Gio.
I guess we'll have to do the rescaling by hand CPU-side, with image/draw.

[sbinet]

well, this is the best I could come up with.
still not on par with what we used to have though...

(I have tried different filters from x/image/draw. the NN is what looked best to my eyes. perhaps we should allow to optionally provide a way to use a user-provided x/image/draw.Scaler ?)

PTAL

[kortschak]

TBH (maybe my eyes are too blurry already) I can't really see the difference.
