I want to draw some graphics that also include a region. What i basically want to do is to do something along the lines
Graphics[
Red, Disk[{0,0},1],
Blue, DiscretizeRegion[RegionDifference[Disk[{1,0},1], Disk[{1.5,0},0.75]]]
]
but the Graphics[] call complains 'An improperly formatted option was encountered while reading a Graphics. The option was not in the form of a rule.' I did my research, manual lookup and googled a lot, but found no understandable explanation how to unleash the power of Regions for my Graphics...
