Comment:

 To handle rotation:

 Create a single fake raster with as many cells as tiles in the coverage.
 Iterate over the x,y dimensions of that raster, and use the ULX and ULY of
 each fake raster pixel to generate a new empty raster with proper ULX and
 ULY values for the rotated component tiles in the coverage.
