Blend Anchor

The blend-anchor parameter chooses which point of the blend layer an explicit blend-x and blend-y land on. The default is the layer’s top-left corner.

It works exactly as mark-anchor does: the value is either an alignment keyword — center, bottom,right, top — or a pair of fx,fy fractions, where 0,0 is the layer’s top-left and 1,1 its bottom-right.

blend-anchor is only read when blend-x or blend-y is set.

Writing the coordinates as decimals makes them relative lengths, so the layout holds at every output width.
