Subject: When converting a gradient to be "Two Tone", take the two colors from either end... 
X-Git-Url: https://git.pterodactylus.net/?a=commitdiff_plain;ds=sidebyside;h=72ff5dd05003d9daf338af91bb42c0541a0293ab;p=synfig.git

When converting a gradient to be "Two Tone", take the two colors from either end of the existing gradient to use as the two colors in the new ValueNode.
