339  * requirements. At present, this is the level at which front end updates
340  * that do not require us to run bw_calcs happen. These are in/out transfer func
341  * updates, viewport offset changes, recout size changes and pixel depth changes.
342  * This update can be done at ISR, but we want to minimize how often this happens.

344  * UPDATE_TYPE_FULL is slow. Really slow. This requires us to recalculate our
345  * bandwidth and clocks, possibly rearrange some pipes and reprogram anything front
346  * end related. Any time viewport dimensions, recout dimensions, scaling ratios or
