Because this object is not functional in itself, but needs to be subclassed.

This is safer because Fl_Screen_Driver has virtual member functions and derived classes.

This simplifies the implementation of Fl_Copy_Surface and Fl_Image_Surface
which now are made to derive from Fl_Widget_Surface.

It is not possible to use fl_graphics_driver in these functions
because when they are called *fl_graphics_driver may have been
deleted. A solution is to use Fl_Display_Device::display_device()->driver()
instead which is always valid.

Fix slow scrolling, line number display, and scrollbars (STR #3272).
Optimized wrap mode - removed unnecessary wrap margin calculations.
The speed-up is significant, but there is still room for improvements.
Refactored parts of the code to make the decisions more modular and
(hopefully) obvious.
This commit also fixes some positioning issues with different scrollbar
alignments and the new line number display.
Fix line number display with wrap mode (hiding text behind scrollbars).
Note: same changes as r11202 and r11205 in branch-1.3.

These options are not enabled by default, but you can enable them by
defining macro DEV_TEST. This adds buttons to toggle wrap mode,
scrollbar positions, and to increase or decrease the window size (width).
Note: this can be used to test STR #3272 and the fixes in a follow-up
commit.
Note: same changes as r11204 in branch-1.3.

This is only for developer info.
Note: cmap.cxx is not included in the library. It is only used to
generate fl_cmap.h.

Some refactoring of a take_focus() function into driver structures (not too happy with it, because it has some kind of bug fix. However, shouldn't *all* Fl_Windows always have an FL_Window_Driver?)

Adding two new driver types for each platform. Fl_..._System_Drivers exist once per application and provide an interface for to file and filename handling, timers, locking, multithreading, etc. .
The Fl_..._Window_Driver class is instantiated once for every window in the system and corresponds closely to (and actually inherits from) Fl_X. The difference now is, that there is one Fl_X/Fl_Window_Driver base class, and one platform version that derives from it.

fl_gc remains usable by the application as a hook into the system.

With this fix drawing works again under Linux. Tiny diff, but ...
Known bugs: opening Fl_Choice dropdown menus crashes the program.
In my experience it takes a while (5-10 seconds) before the crash
occurs. Maybe an endless loop that eventually "kills" the stack ?

I moved all timer related (X11) stuff from src/Fl.cxx to
src/drivers/X11/Fl_X11_Screen_Driver.cxx and added externals as
done by Ian in a previous commit for the WinAPI screen driver.
I did not (yet) remove the code from Fl_x.cxx though, but disabled it. See:
#if (0) // *FIXME* moved to src/drivers/X11/Fl_X11_Screen_Driver.cxx
Current state is that FLTK can be compiled and linked again (under Linux)
but doesn't work (shows empty windows only).
I thought it was worth to commit my work, but can't check what's going on
right now - other devs should feel free to continue this.
PS: the new code in src/drivers/X11/Fl_X11_Screen_Driver.cxx was just
dropped in, keeping the right order for usage of static helper functions,
but should be fixed in all regards (order, logic, ...).
