-/* The fragment shader uses the UV coordinates to calculate whether it is in
-   the T, R, B, or L border.  These are then mixed with the border color, and
-   their inverse is mixed with the fill color, to calculate the fragment color.
-   For example, if we are in the top border, then T=1, so the border mix factor
-   TRBL=1, and the fill mix factor (1-TRBL) is 0.
-
-   The use of pixel units here is handy because the border width can be
-   specified precisely in pixels to draw sharp lines.  The border width is just
-   hardcoded, but could be made a uniform or vertex attribute easily enough. */
