Replace some if statements with a switch statement 

The switch case statement allows the compiler to optimize code. More
specifically, if the values are densely packed, then the compiler may
generate a jump table. The switch statement also looks cleaner.

As for the if statements in adjustWorkArea(), they were overlooked by
me after LayerSurfaceV1Interface::exclusiveEdge() had been introduced.
