Also, unittest added (scrollbar size) to test these changes.
Thanks to Albrecht for testing/peer review.

+ Replaced uninitialized C parameters archaisms, by on the fly C++ local var. decl.
Not only it will be more optimized by modern c++ compilers,
code is easier to read, maintain and debug and is shorter.
Most local variables are now explicitly intialized when declared.
+ Replaced some non const vars by const equivalents when required.

+ Modified selection buffer access methods to return const Fl_Text_Selection pointers. Added a non const get method for the main selection buffer.

+ Made char * text() const., this method should be further checked for UTF8 compat.
+ Added a fixme comment to remember we must check for the potential incorrect
assumption that that a buffer size equals the string length + 1.
+ Correct a protected attrib. typo as we don't need to care about ABI compat. for 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().

STR 2185 and in fltk.development to prevent memory leak. The removed comment
about a crash in XFree86: _XlcCreateDefaultCharSet() appears to be outdated
(probably from 2005/2006).

this is the first stage in putting tutorial type info together.
next stage is to put the functions into related groups for explanation.
corrected minor typo in Fl.H
