(svn r7449) -Codechange: Rename _path to _paths as it is technically more correct, but mainly because
it interferes with OS/2 symbol in libc (psmedley)

(svn r6925) -Codechange: Be more strict with widget distinctions. WWT_PANEL is only plain panel,
WWT_IMGBTN must contain an image for drawing. Renamed WWT_PANEL_2 to WWT_IMGBTN_2
because that is what it is. Added WWT_PUSHBTN that is either just a pushable button,
or a textbutton, which text's drawn dynamically independent of widget.

(svn r6793) -Fix(5464): When checking items on an array, make sure to respect boundaries(jez).
Made some comments code style compliant

(svn r6631) -Codechange: Use accessors for click_state.
Another step toward merging XTDwidget.
The only two files not converted (window.h and widget.c) will be done at the very last commit)

(svn r6619) -Codechange: Use accessors for disabled_state.
Another step toward merging XTDwidget.
The only two files not converted (window.h and widget.c) will be done at the very last commit)

(svn r5464) [Behaviour Fix] : When starting the game, the system will now verify the presence of music files in gm forlder.
A song can now be removed from the programmed list (in custom list 1 and 2) by clicking on it.
Added music.c[ch] files, to make it all a bit cleaner.
Now, the name of the gm file is associated with the title of the song.

(svn r3181) -Bracing
-Indentation
-Whitespace
-DeMorgan's Law
-Test with NULL or 0 for non-booleans
-'\0' instead of 0 for chars
-Remove redundantly redundant comments (like DoFoo(); // Do foo)
-Join multiple short lines with a single statement
-Split single lines with multiple statements
-Avoid assignments in if

(svn r2112) -Fix: ExtMidi no longer halts the game while starting a song
-Fix: Redirect stdin/stdout/stderr of the ExtMidi process to /dev/null, to prevent it from writing to the terminal
While here give the ExtMidi functions canonical names

(svn r1348) -Feature: resizable windows. Read the comment in window.h to find out
how the system works. All useful windows are already made resizable. Enjoy :)
-Fix: fixed some GUI-glitches and flaws along the way

(svn r901) Small step in the process to clean up the DPARAM mess:
- reduce to 2 sizes (*DParam64 for 64bit values, *DParam for the rest)
- use inline functions instead of macros
- add assert()s to check for buffer overruns

(svn r815) Include strings.h only in the files which need it.
This should reduce the compile time after altering english.txt by about 1/3, because "only" 62 instead of 90 .c files must be recompiled.

(svn r177) -Fix: padded out Widget code to solve warnings on C99 compiler (Tron)
-Fix: added WIDGETS_END macro for WWT_LAST which does this for all last widget-types
