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 fix is to use the X11 graphics driver's line_delta_ private member variable also when drawing complex
shapes with fl_begin_loop(). The gtk+ scheme does use fl_begin_loop() to draw its frames.

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.

and other font stuff. Fixed horizontal and vertical line
drawing to include last pixel. Added stippling to focus rect.
Added point drawing (slooow).

Better complex region cleanup - should be compete now...

However I did disable the complex region optimizer - too tired to get
the pointers right... .

Next: intersetcing a complex clipping region with a rectangle

fallbacks, added emergency font as an asset, added graceful
behavior when absolutely no font could be loaded.
Next: add other font related calls, add clipping

Next: add other font related calls, add clipping,
add font paths for package resources
git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12766 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
Next: add caching, add other font related calls, add clipping,
add font paths for package resources

Next: cleanup, document, add caching, add other font related calls,
add clipping, add font paths for package resources

This code is still a total mess and incredibly inefficient.

files, further fostering follows.
Or, to put it bluntly, I forgot how the font system works, and now I am
digging through the implementations of other drivers, carrying bits and
pieces together. But you know that I will clean my files eventually... .

render better text, so I have something to test this on.

This code is not very beautiful, but the resulting class should be
easy to use. A range-based loop can be used to find all relevant
clipping rectangles for a drawing call.

Make clipping methods non-virtual so they can be inlined.
