* Thanks to the CPU's new block-based memory manager that allows us to sparse-allocate memory
* in 4K increments, updateScreen() can also ask the CPU for the "dirty" state of all the blocks
* underlying the video buffer, bypassing the update completely if the buffer is still clean.
* (in 4Kb increments on 20-bit buses, 16Kb increments on 24-bit buses), updateScreen()
* can also ask the CPU for the "dirty" state of all the blocks underlying the video buffer,
* bypassing the update completely if the buffer is still clean.
*
* Unfortunately, that optimization is defeated if our count of active blink elements is non-zero,
* because we must rescan the entire buffer to locate and redraw them all; I'm assuming for now
