Avoid using QRgba64 for buffers

Browse Source 
Benchmarking showed most time rendering in rgb64 mode was spend on
memsetting the buffers because they were not declared with a primitive
type.

This patch changes the buffers to quint64, but leaves refactoring
function arguments to a later patch in the dev branch.
