The follwing are defines for types used in the LCD-driver and the
emWin layers on top of that. Since "C" does not provide data types of
fixed length which are identical on all platforms, this is done here.
For most 16/32 controllers, the settings will work fine. However, if
you have similar defines in other sections of your program, you might
want to change or relocate these defines, e.g. in a TYPE.h file.

Some settings in the configuration may conflict with the values required
in the Simulation. This is why we ignore the target settings for data
types and use the correct settings for the simulation.
(U32 could be defined as long, which would yield a 64 bit type on
the PC)

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.
