* for device capabilities
The following is the list of device capabilities which can, but do
not have to be implemented in the driver. This way the driver can be
enhanced in the future without affecting the driver interface,
keeping older drivers compatible.
More DevCaps can always be added in the future, as older drivers
are guaranteed to return 0 for all unimplemented features or queries.
The values below define the legal parameters to the LCD_GetDeviceCaps
and the LCD_GetpCapFunc routines.
