   7  * A newstyle startup code for resident display drivers.
   8  *
   9  * Now it's the job of the driver to add ifself to the system.
  10  * The driver does not have to be a library anymore, it can be
  11  * plain executable which is started from DEVS:Monitors.
  12  *
  13  * The job of driver startup code is to create all necessary
  14  * classes (driver class and bitmap class) and create as many
  15  * driver objects as possible. Every object needs to be given
  16  * to AddDisplayDriverA() in order to become functional.
  17  *
  18  * Hosted drivers are also responsible for registering own input
  19  * drivers if needed.
