 +===== Priority =====
 +
 +When setting up clock callbacks in orx, we need to specify a priority for the callback. This priority value specifies when a callback will occur during the execution within a given frame.
 +
 +  - Render all viewports/objects & emit all the draw calls (using the state of the previous frame), let the GPU work as early as possible (priority = HIGHEST)
 +  - Update inputs (physical polling w/ priority = HIGHER, input module w/ priority = HIGH)
 +  - (Scroll only) Game Update (if no Scroll, that's where one should likely put their logic as well, ie. priority = NORMAL)
 +  - Update all objects and linked structures (anim, sound, FX, etc., priority = LOW)
 +  - Update the physics simulation (priority = LOWER)
 +  - End the render frame, ask for presentation (priority = LOWEST)
