On MacOS and other systems that support kerning, dragging a selection over text would
make the text to the right of the selection jump in x by a fraction of a pixel. The new code
makes sure that the text stays rock solid.
Recent Linux distribution have replaced the freetype-config command
by pkg-config. The fix tries the new procedure with pkg-config and
falls back to freetype-config if the new procedure fails.
The given position to insert a new item was not checked against the
valid range so the program could crash if a position less than zero
or greater than children() was given. The position is now clamped to
the valid range, i.e. the item is either prepended or appended.
Fixes issue #18.
macOS normally previews a dead key and then replaces the preview by the final text
after the second key is typed.
macOS ≥10.7 also opens an auxiliary window to help choosing among possible characters
after some keys (e.g., n, c, o, a) are pressed and maintained for a while.
The problem fixed here is that after an auxiliary window has been used,
dead keys are no longer previewed.
That problem emerged at some undetermined point before 10.14 and after 10.7.
o Added mention of drag+drop / FL_TREE_SELECT_SINGLE_DRAGGABLE
to list of features on main Fl_Tree doxygen page.
o Whitespace mods to FL_TREE_SELECT_* to fix doxygen 1.8.5
whitespace sensitivity that was causing single sentence
to break into two when spanning multiple "///>" comments
for last item in an enum (doesn't end in ",")
The intention is to improve (and minimize) diffs when dependencies
are changed and `make depend' is executed.
(1) use `makedepend ... -w 20'
(2) `sort -u' the resultant file with some more "magic".
(1) makes sure that there is only one dependent file per line,
(2) makes lines unique since `makedepend' can output one file
many times which is redundant and makes diffs hard to read.
This uses 'mv', 'grep', and 'sort' in all FLTK library Makefiles.
Image libraries are intentionally left for a later update.
test/fracviewer.cxx wouldn't be compiled if the ABI version was
changed with configure and `make' was executed w/o `make clean'.
Add 'fracviewer.cxx' to list of source files to fix this.
Also add missing unittest_scrollbarsize.cxx to dependencies of
unittests.o.
Finally run `makedepend' to update dependencies.
Note: cherry-picked from branch-1.3 and adjusted to fit master (1.4)
