ff647fccb0
Currently to change vector layer properties, you need to grab the VectorLayerOptions and then grab its FillOptions or the StrokeOptions to make changes. To make this process more self-contained, this patch creates a gimp_vector_layer_set () function that operates in the same manner as gimp_text_layer_set (). This patch adds properties for Fill - Stroke properties will be added in a follow-up commit. This also adds automatic tracking for Undoing/Redoing vector property settings. A demonstration of its use in DnD colors and patterns onto the layer dock is included.
