Also, change arguments of void Fl_Window::capture_titlebar_and_borders() from
Fl_RGB_Image to F_Shared_Image so, in the future, scaled images having

This new member function returns a high resolution bitmap image scaled to the adequate
drawing size. This allows to create a bitmap image able to fill all pixels of a high resolution
display. This is functional only for the Mac OS platform. On other platforms,
the new member function returns an unscaled bitmap.

and whether we are printing: virtual int Fl_Graphics_Driver::has_feature(driver_feature feature)
This is also because it is not convenient to derive a printer-specific driver with its own
implementation of virtual functions when this implementation differs only in one line of code.
2) Solved the problem of inclusion of non public header by the public header FL/Fl_Device.H:
bracket this with #if FL_LIBRARY / #endif so this non public header is included only when building
FLTK itself.
3) Removed several (but not all) of the FLTK_ABI_VERSION guards that are no longer
useful for code targeting FLTK 1.4.

2) Advance branch-1.3-porting with new function Fl_X::capture_titlebar_and_borders()

Improved handling of the situations where a subwindow is created,
hidden, the parent window resized, and the subwindow shown,
with a new size. This change no longer sends setFrame: or setFrameOrigin:
messages to hidden subwindows. Instead, subwindows acquire their correct
size and position when they are shown again and Fl_X::map() is called.

and builds itself the image when a window with subwindow is miniaturized. That is mostly OK, but it fails when a window
containing a subwindow is miniaturized (a mini image is computed), deminiaturized, the subwindow is removed
or hidden, and the window is miniaturized again: the old mini image is used, and that is not appropriate.
The solution is to remove the FLTK-computed mini image when a window with subwindow is deminiaturized.

Methods Fl::event_x_pixel() and Fl::event_y_pixel() committed at r.10941
are removed. Instead method Fl_Gl_Window::pixels_per_unit() is added.

it covers the dock and the system menu bar. The default behavior of a subwindow of such
a fullscreen window is to be prevented to cover the menu bar (which makes not much sense
because this bar is covered by the main window). If the location of the subwindow within
its parent window expected by FLTK would have it cover the menu bar, Mac OS moves
it down. The subwindow therefore does not lie where FLTK wants it.
This patch overrides the adequate method of the NSWindow class to prevent this bad behavior.

The -[NSWindow makeKeyAndOrderFront:] message used to make the window appear on the screen,
but, starting with 10.10 (approximately), this changed, and it became necessary to query for events
for a new window to appear on the screen. With 10.11 two event messages are needed.
The solution is therefore to implement Fl_Window::wait_for_expose().
- Calling NSDisableScreenUpdates()()/NSEnableScreenUpdates() before and after window updates
greatly accelerates multi-window update operations.

graphics context to draw to a window. This requires Mac OS 10.4.
The advantage is that it is possible for a secondary thread to call
Fl_Window::make_current() without needing to create an autorelease pool.
We save the native graphics state, and also the state with origin at top.
Fl_X::q_release_context() restores the graphics state twice to return to
the native state. This allows to use a single graphics context for a single
window and a single thread.
Under 10.3, we have to create a new NSGraphicsContext when Fl_Window::make_current()
is called directly, so that secondary threads cannot call Fl_Window::make_current() without
having created an autorelease pool.

All changes are mac-specific, except a very minor change in file src/gl_draw.cxx
where string drawing wrongly claimed to support @symbol, not possible
because symbols are drawn using non-GL primitives.
Unchanged application code can use the new FLTK code.
In addition, the new code allows mac applications to draw OpenGL scenes
at high resolution on so-called 'retina' displays, but this requires some
support from app code. They must call, before opening GL windows,
Fl::use_high_resolution(1);
and change their glViewport() calls as follows
glViewport(0, 0, pxel_w(), pixel_h());
This uses 2 new member functions of the Fl_Gl_Window class,
pixel_w() and pixel_h() returning the window dimensions in pixel
units, that is, twice the w() and h() when the window is mapped
on a retina display.
