ScaleFast: issue with anchors and transformation of components

Anchors

ScaleFast’s output does not include anchors. It would be handy to have those.

Transformation of components

When I work with components in combination with certain transformations (like arrows that are based on a single glyph that is flipped and/or rotated) these are not always calculated as expected. In the following example all negative values are turned into positive ones in the output ufo.

font 1:
-1, 0, 0, -1, 807, 630

font 2:
-1, 0, 0, -1, 807, 630

output:
1, 0, 0, 1, 807, 630

Having the same wishes with anchors and components here. Component changes are currently wacky!

Would be great for common font info to be preserved or interpolated when making a New Font.
Also guidelines if possible.
Layers?
