175 * requirements. At present, this is the level at which front end updates
176 * that do not require us to run bw_calcs happen. These are in/out transfer func
177 * updates, viewport offset changes, recout size changes and pixel depth changes.
178 * This update can be done at ISR, but we want to minimize how often this happens.
180 * UPDATE_TYPE_FULL is slow. Really slow. This requires us to recalculate our
181 * bandwidth and clocks, possibly rearrange some pipes and reprogram anything front
