This builds on the mechanism that Albrecht added to test flipped and inverted image drawing, but allows the settings to be changed at runtime rather than at compile time as previously.
I'm commiting it here for testing use in the porting branch, but I'm not happy I've really tested it enough yet so reluctant to commit it in the main fltk-1.3.x branch until this code has been reviewed and tested by others.

This commit defines additional preprocessor macros to enable testing
negative d and ld arguments of fl_draw_image(). Documentation (test
scenario) has also been improved.
Same commit as in branch-1.3, svn r11269.

are implemented as compiler macros and can only be edited manually to test
different implementation details.

made consistent with other platforms, that is, the 4th byte of each pixel is ignored
instead of treated as transparency data.
In the future, the fl_draw_image() signature may be extended with another argument
that would describe if and how transparency information is available.

Note: fl_draw_image() supports transparency (alpha channel) currently
only on Mac OS X.
This needs to be fixed for other platforms !

(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...

with Quickdraw worked) in src/Fl_Images.cxx.
Changed test/unittest_images.cxx to use Fl_RGB_Image::draw() to draw images
with alpha channel, because the current version of fl_draw_image()
supports alpha channels only on Mac. Tested on Windows[1], Linux, and Mac.
[1] Windows with GDI drawing doesn't work yet for gray+alpha (STR 2105).
To do: Check, if fl_draw_image() should support alpha channel images
on all platforms or not at all. The current documentation mentions only
RGB and gray scale images. IMHO the behavior is undefined for values of
abs(d) == 2 and abs(d) > 3. See also fl_draw_image_mono().
