Please invert the direciton of this; tile manager should say
m_client->canDoAnotherCheapRasterTask()

then we do one
->didPerformCheapRasterTask(amount of time consumed)

have lthi do the bookkeeping

Done. I took the "Task" out of the names to keep things consistent -- only
rasters done by the workers are tasks.
