There is coverage composed of two overlapping tiles
(size of tiles does not matter now):

+--------+
|        |
|  +-----|------+
|  |     |      |
|  |     |      |
+--+-----+      |
   |            |
   +------------+

(I hope my ASCII-art format is preserved)

How do you render it in a basic client (desktop, web, whatever)?
