/**
|
|
* @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 normaly uninteressted 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 uninteressted, 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".
