If any cursor manager wants to get the estimate, then that process should call the filter function, eand read the mouse from it an update the filter. Thus, priority is automatic, processes in a hurry to grab it will pay with clock ticks.
The libev can read and queue the events in a folding buffer, only the last two or three e available. So, upon a call to red, the caller forced to run the recent buffer through the motion filter.
A great solution for snippets as we will see independent threads from different snippets writing ttheir own rectangle from their own io driver. Each of these cursor users pay a cost in tracking the ting inside or outside the window. So we standardize on the best mouse tracker in the business, number one algorithm; and multi thread id,we can rack one virtual cursor s a composed of the cursors positions in all the rects. Process ticks apportioned as above. Very fast, very accurate, exposed.
