f02593cf1a COLRVariationMerger: fix logic in convertSubTablesToVarType 
Before we were too greedy in the way we converted subtables to VarType. E.g. If a PaintTransform wrapping a PaintRadialGradient contained variations in the Affine2x3, we would incorrectly convert also the gradient's ColorLine (and ColorStops) to VarColorLine, VarColorStop, etc. (even if the gradient was not variable!). Instead we want skip traversing a given subtable including its children when the predicate doesn't match.

19f5965aa0 chore: Included githubactions in the dependabot config 
This should help with keeping the GitHub actions updated on new releases. This will also help with keeping it secure.

Dependabot helps in keeping the supply chain secure https://docs.github.com/en/code-security/dependabot

GitHub actions up to date https://docs.github.com/en/code-security/dependabot/working-with-dependabot/keeping-your-actions-up-to-date-with-dependabot

c63b84db7e Update how table packing falls back to fontTools from harfbuzz. 
Introduce three compilation modes:
1. Pure python: only uses the existing fonttools packing and overflow resolution.
2. Harfbuzz+python: uses harfbuzz packing and python overflow resolution. Extensions are allowed to be shared.
3. Python fallback: if harfbuzz+python runs out of resolution options, this disables extension sharing and only uses python packing. Once it succeeds control is passed back to the harfbuzz packer to produce the final packing with extension sharing enabled.

83f69028a3 chore: Set permissions for GitHub actions 
Restrict the GitHub token permissions only to the required ones; this way, even if the attackers will succeed in compromising your workflow, they won’t be able to do much.

fc982c643b colorLib: add option to disable PaintColrLayers' reuse of layers from LayerList

0d7d7d4e11 [varLib.iup] Rewrite force-set conditions & limit DP lookback length 
This does two things:

Fixes forced-set computation, which was wrong in multiple ways.
Debugged it. Is solid now... Famous last words.

Speeds up DP time by limiting DP lookback length. For Noto Sans,
IUP time drops from 23s down to 9s, with only a slight size increase
in the final font. This basically turns the algorithm from O(n^3) into
O(n).

c34ff0d474 [varLib.merger/errors] fix undefined exception name 
The exception UnsupportedFormat was defined and then redefined with the same name in varLib.errors, and imported twice from varLib.merger, probably as result of a sweeping find/replace.
Rename it 'InconsistentFormats' as originally intended.
