Graphics drivers now use up to 6 virtual member functions to support Fl_Image
drawing in the context of GUI and image rescaling :
virtual void draw_pixmap(Fl_Pixmap *pxm, int XP, int YP, int WP, int HP, int cx, int cy)
virtual void draw_bitmap(Fl_Bitmap *bm, int XP, int YP, int WP, int HP, int cx, int cy)
virtual void draw_rgb(Fl_RGB_Image *rgb, int XP, int YP, int WP, int HP, int cx, int cy)
and
virtual void draw_fixed(Fl_Pixmap *pxm, int XP, int YP, int WP, int HP, int cx, int cy)
virtual void draw_fixed(Fl_Bitmap *bm, int XP, int YP, int WP, int HP, int cx, int cy)
virtual void draw_fixed(Fl_RGB_Image *rgb, int XP, int YP, int WP, int HP, int cx, int cy)

The docs of class Fl_Image and of Fl_Image::scale() are beefed up.

Each image has now two sizes implemented as follows:
- the pixel size is stored in private members pixel_w_ and pixel_h_
with public accessors pixel_w() and pixel_h()
- the FLTK size is stored in private members w_ and h_ and read by w() and h()
- when the image is constructed, the two sizes have the same value
- the protected w(int) and h(int) member functions set both FLTK and pixel sizes.
- the public scale(int, int) member function is essentially nothing but
set the FLTK size and don't change the pixel size.
- when the image is drawn, its FLTK size determines how big it is drawn, its pixel
size determines how much data are available to draw it.
FLTK 1.3.4 with FL_ABI_VERSION=10304 contained an equivalent member function
but only for the Fl_Shared_Image class.

Removed obsolete '\todo' item from docs (done with recent commits).
Removed redundant code from label assignment (e.g. use FL_IMAGE_LABEL
instead of label type assignment + use of _FL_IMAGE_LABEL).
See recent commits.

Consequently, remove the trailing _ from its name reserved for private class members.

This allows to use the virtual function mechanism to adapt scaled image drawing both to the
image type and the graphics driver type.

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.

- change image caching variable types to uintptr_t
- added driver function to uncache image data
- cleaning up (Xlib and GDI will likely throw syntax errors. Trying to fix ASAP)

Removed a false comment I just added.
Removed FL_PORTING ifdef that is no longer needed

with Fl_Widget::type(). Added a setter function Fl_Device::class_name(const char *).

conflict with Mac OS X/gcc 3.x name clash when compiling with obj-c.
Also made them private instead of public.

(1) adding Fl_Device class (and more) for device abstraction
(2) adding Fl_Pinter class (and more) for printing support.
Todo: Code cleanup, update dependencies, remove/replace test print window.
I'm looking into converting the test window popup in a global shortcut
that would pop up the print dialog now...

In regard to CG Text drawing vs. the new ATSU Text drawing: I now remember why I did not ATSU in the beginning: STDU does not use the CG clipping area or text pen settings. So, if you plan on using the current SVN with --enable-quartz, please be aware that you will not have any text clipping or any other text color than black.
Finally, I added code to FLTK on OS X that retreives the selection color from the system instead of assuming dark blue. I am not entirely confident about this change as it may require OS X 10.4 . Feedback appreciiated.
