Subject: Add "By Layer Default" blend method to the Toolbox Defaults widget.
X-Git-Url: https://git.pterodactylus.net/?a=commitdiff_plain;h=34661891b55d1b54f96955755b4cbd099039acc9;p=synfig.git

Add "By Layer Default" blend method to the Toolbox Defaults widget.
It allows the user let the layer itself use the blend method defined by the layer by default.
For example, blur layer uses Straight blend method by default and Bevel uses Onto.
The default blend methods by layer can be discussed or changed later.
