ReadSVG 4.0

[rodlie]

As discussed in NatronGitHub/Natron#970 add basic transform to ReadSVG.

• Create a cairo helper class (we have more cairo-based plugins that can share code)
• Integrate OFX transform helpers
• Add transform support
• Test new params (work as expected?)
• Add unit tests for new functions

Got POC working in the cairo branch, will continue later this week.

So, things seems to work. Needs more testing, I only used Ubuntu 22.04 with Natron RB-2.5.

But, keyframes don't work (and no interact, not that important)

(node resize is not related, this is a Qt5 issue)

hum any idea why keyframes/animation don't work?

Unsure, probably something in IOSupport.

Will check when I get the time, maybe later tonight else this weekend.
