-//   | |        | |
-//   | |        | |
-//   |_|________|_|

-// shows the upper part of the upper left corner. The bottom triangle would similarly be split

-//   |\  \   |
-//   |  \ \  |
-//   |    \\ |
-//   |      \|

-// The center of the fan handles the curve of the corner. For roundrects where the stroke width
-// is greater than the corner radius, the outer triangles blend from the curve to the straight
-// sides. Otherwise these triangles will be degenerate.
-//
-// In the case where the stroke width is greater than the corner radius and the
-// blur radius (overstroke), we add additional geometry to mark out the rectangle in the center.
-// This rectangle extends the coverage values of the center edges of the 9-patch.

- * - Removed transformations applied on the caster rect since the caster will be in local
