How would that scenario handle cursor animation? Many "The system is busy now" type cursors are animated. Say cursor animation requires 15 different images per second. Can the card store those images in its RAM, and just cycle through them? Or is it required to PIO cursor image data to the card 15 times per second? In the last case, would that be a problem?
