Added filename_setext() macro for FLTK_1_0_COMPAT.

Fixed copy() methods so they don't overflow the source image buffer.

<H3><A name="boxdraw">Boxes</A></H3>
<P>FLTK provides three functions that can be used to draw boxes
for buttons and other UI controls. Each function uses the
supplied upper-lefthand corner and width and height to determine
where to draw the box.
<H4><A NAME="fl_draw_box">void fl_draw_box(Fl_Boxtype b, int x, int y, int w, int h, Fl_Color c);</A></H4>
<P>The first box drawing function is <CODE>fl_draw_box()</CODE>
which draws a standard boxtype <CODE>c</CODE> in the specified
color <CODE>c</CODE>.
<H4><A NAME="fl_frame">void fl_frame(const char *s, int x, int y, int w, int h);</A></H4>
<P>The <CODE>fl_frame()</CODE> function draws a series of line
segments around the given box. The string <CODE>s</CODE> must
contain groups of 4 letters which specify one of 24 standard
grayscale values, where 'A' is black and 'X' is white. The order
of each set of 4 characters is: top, left, bottom, right. The
results of calling <CODE>fl_frame()</CODE> with a string that is
not a multiple of 4 characters in length are undefined.
<P>The only difference between this function and
<CODE>fl_frame2()</CODE> is the order of the line segments.
<H4><A NAME="fl_frame2">void fl_frame2(const char *s, int x, int y, int w, int h);</A></H4>
<P>The <CODE>fl_frame2()</CODE> function draws a series of line
segments around the given box. The string <CODE>s</CODE> must
contain groups of 4 letters which specify one of 24 standard
grayscale values, where 'A' is black and 'X' is white. The order
of each set of 4 characters is: bottom, right, top, left. The
results of calling <CODE>fl_frame2()</CODE> with a string that is
not a multiple of 4 characters in length are undefined.
