Edge Attachment Coordinates
The fifth through eighth coordinates of a position coordinate_list, controlling how the element resizes with its parent.
Kind: concept
For coordinate_lists that define a position, the 5th-8th items in a coordinate_list are used to specify "edge attachment". This controls how the position/size of the item changes in relation to changes of the parent size. These values are usually within 0..1, where 0 means that a change in the parent size does not affect a change in this coordinate, and 1 means that a change in the parent size changes this coordinate similarly, and 0.5 means that an increase of 2 pixels in the parent size will increase this coordinate by 1.
For other types (fonts, margins), the meanings of these items is specific to those types.
