* Don't wait for VSync if we're in IRQ context, since (a) IRQ handlers shouldn't take lots of time, and (b) it may hang the system. Fixes https://www.riscosopen.org/tracker/tickets/424 * Extend the DPMSUtils-inherited "don't wait for VSync if HSync output is off" fix to also deal with the case where VSync output is off, since it's reasonable to assume that turning off VSync output could also prevent the CPU from receiving the associated interrupts.
