SynEdit.Gutter.AutoSize
SynEdit.Gutter.Width

SynEdit.Gutter.Parts.Count
SynEdit.Gutter.Parts[n].AutoSize
SynEdit.Gutter.Parts[n].Width

SynEdit.Gutter.Parts.ByClass[TSynGutterLineNumber, 0]

All of that also in object inspector. So you can also fine tune, what 
should be in the gutter


If you want to keep the lower one autosized. There is also
SynEdit.Gutter.OnResize

BUT it is currently used by SynEdit. That needs to be fixed.
If you use it, store the existing value and call it when triggered
