/**
* @defgroup dirty Dirty
*
* Handles the repaint of some part of the screen.
*
* Some places in the code are called functions which makes something "dirty".
* This has nothing to do with making a Tile or Window darker or less visible.
* This term comes from memory caching and is used to define an object must
* be repaint. If some data of an object (like a Tile, Window, Vehicle, whatever)
* are changed which are so extensive the object must be repaint its marked
* as "dirty". The video driver repaint this object instead of the whole screen
* (this is btw. also possible if needed). This is used to avoid a
* flickering of the screen by the video driver constantly repainting it.
*
* This whole mechanism is controlled by an rectangle defined in #_invalid_rect. This
* rectangle defines the area on the screen which must be repaint. If a new object
* needs to be repainted this rectangle is extended to 'catch' the object on the
* screen. At some point (which is normally uninteresting for patch writers) this
* rectangle is send to the video drivers method
* VideoDriver::MakeDirty and it is truncated back to an empty rectangle. At some
* later point (which is uninteresting, too) the video driver
* repaints all these saved rectangle instead of the whole screen and drop the
* rectangle informations. Then a new round begins by marking objects "dirty".
*
* @see VideoDriver::MakeDirty
* @see _invalid_rect
* @see _screen
