-/* GJA --
- * After finding three kinds of errors in this single function,
- * (requiring modifications to be made at at least 10 places,
- * I decided to REWRITE the body of the xf4bppTileRect function from scratch.
- * This version simply computes all relevant margins in advance, and does
- * not try to reuse temporary variables. I leave that to the compiler.
- * (This was a maintenance and robustness nightmare anyway.)
- * The code is pretty obvious: all margins, coordinates, and numbers of tiles
- * are computed before drawing starts.
- * Notice that the margins consist of incompletely drawn tiles. Therefore
- * we need offsets in the data for the left and upper margins.
- * The right and lower margins are also incomplete, but start at offset 0
- * in the data. They just end at awkward offsets. 
- * The center block, by definition, consists of fully drawn tiles.
- * Perhaps we could leave out some if's. But why bother? It would decrease
- * robustness.
