I'm -1 on such API's as Fl::hint(int, int, int...). They are confusing
and hard to implement (need switch(..) etc.). Also, extension of the API
using other datatypes would be possible but less obvious.

I'd propose to introduce a new (static?) object type like Fl_Screen or
similar with virtual methods that can easily be extended (one method per
logical function).

An Fl_Screen class array with some accessor would also solve the increasing number of Fl::screen_...() methods.
 
The methods above could then be:

Fl_Screen::format(FL_SCREEN::LANDSCAPE_ONLY);
Fl_Screen::landscape_width(1024);

Preferably inside a if (platform==Android) { ... }. On a desktop machine, those calls alone would be misleading, even if they are not implemented in the driver. But yeah, ok. I see your point.

The device type would not be necessary because it would be "known" by
the (virtual) method implementation.
(...) 
This is consistent with the current driver model and getter methods
would be very simple to call, supposedly only in driver related code parts.

OK, makes sense. I'll have to implement an automated version of this first anyway, and then I will get back to a possible API.
