Small fixes in IFS Fractal and other Render filters
Small papercuts from continued filter and docs testing.
- Add a missing heading for
Spatial Transformation
section in IFS Fractal - No section number for IFS Fractal was listed in https://testing.docs.gimp.org/2.99/en/filters-render.html since the link wasn't to the page itself but to an anchor lower down on the page.
- Remove a "legacy" for the new checkerboard plug-in
- Anti-aliasing is written with a hyphen in qbist
- Turbulence option for Plasma starts at 0.0
Edit: Also updated the image for qbist, and mentioned the "Pattern" label added in gimp@708f075f
