Some border lines were too short or too long, the shading code would draw
too many shaded lines, and the code was hard to understand.
With this commit all background pixels of the box are drawn exactly once.
The border lines are consistent, but some pixels of the border are not
drawn at all so the background shines through. This is intended for
backwards compatibility.
A minor change is that the drawn background does no longer overlap the
border lines. Hence undrawn pixels that previously displayed the colored
box background are now transparent and show the parent's background color.
This commit adds comments and implementation notes to make the code
easier to understand and better maintainable (hopefully).

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

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 is a preliminary patch to enable linking with pango on MacOS
when fltk-config is used. A better solution is under development.

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.

fl_rectf is so far the only function that uses the complex clipping
region successfully. Code is slow, but works.

Clipping areas are calculated for overlapping windows, named "Desktop
Windows". The first level implementation works if the resulting complex
region is just a rectangle. Higher complexity (sub-rectangles) is next.

Complex clipping is needed to allow popup dialogs and menu window while
still correctly rendering windows that are "below" those popups.

Back to 16-bit coordinate limit clipping (actually +/- (2**15 - 8).
The clipping range is now constant, symmetrical, and stored in the
driver object.
Also fixed a bug in Liang-Barsky line clipping algorithm.
