// Frequency (ms) with which the core performs timer tasks

// VOLUME_SAMPLE is the time beyond which we will take another sample of
// the bounds accumulation data. If the screendata accumulated in this
// time is less than BOUNDS_ACCUM then we will try and send it immediately
// otherwise we wait until the orders have slowed down.
//
// UPDATE_PERIOD is the absolute maximum time between attempts to send data
//
// ANIMATION_SLOWDOWN id how many times we attempt to send mem-scrn blits
// over a PSTN connection.
//
// ANIMATION_DETECTION the interval, in mS, below which we determine the
// app is performing animation. Must be low otherwise we slowdown during
// rapid typing. The algorithm simply looks for repeated memblts to the
// same area
//
// DCS_ORDERS_TURNOFF_FREQUENCY
// The frequency of orders above which we start time slicing order
// transmission in order to give the host system a chance to draw the
// orders without having to send them in individual network packets.
//
// DCS_BOUNDS_TURNOFF_RATE
// Very important for performance of typing in Word that this value is not
// too low, since Word can generate 50K per keystroke. On the other hand,
// it is important not to allow the capture of screendata until after an
// app that does a lot of blitting to the screen has finished.
//
// DCS_BOUNDS_IMMEDIATE_RATE
// To avoid sending excessive amounts of screendata we only send at the
// most ten times per second. However, if the volumes are small then we
// override this to reduce latency
//
//
// The other rates control individual timer functions - see adcsapi.c for
// further details
// Note that the IM period is less than the likely rate of this function
// being scheduled. This is set low so that we will, in general, call IM
// periodic every time to keep mouse moves flowing, but it will not be
// called repeatedly if there are several wakeups pending within a single
// scheduling cycle.
