The UsesOfSymbolAtPoint can now use ActWin (as alternate to Quickfix
window).
Options:
'tailor-uses-of-symbol-at-point-window' : 'actwin' (default) or 'quickfix'
Per use of the ActWin, there are numerous Options. For now this is
an initial set that control how lines in Scala files and in the ActWin
itself are highlighted:
Use sign in Scala files (all lines highlighted at once):
'tailor-uses-of-symbol-at-point-use-actwin-display-scala-sign-enable' : 0 or 1.
Use a (sign-based) color line in Scala files (current line only):
'tailor-uses-of-symbol-at-point-use-actwin-display-scala-color-line-enable' : 0 or 1.
Use a color column in Scala files (current column only):
'tailor-uses-of-symbol-at-point-use-actwin-display-scala-color-column-enable' : 0 or 1.
Use a cursor line in ActWin (current line only):
'tailor-uses-of-symbol-at-point-use-actwin-display-actwin-cursor-line-enable' : 0 or 1.
Use a highlight line in ActWin (current line only):
'tailor-uses-of-symbol-at-point-use-actwin-display-actwin-highlight-line-enable' : 0 or 1.
Use a (sign-based) color line in ActWin (current line only):
'tailor-uses-of-symbol-at-point-use-actwin-display-actwin-sign-enable' : 0 or 1
Ultimately all ActWin commands and highlight features (colors and text)
will be Option based.
