XSetLineAttributes(diplay, gc, line_width, line_style, cap_style, join_style)
Display *display = Dsp;
GC gc;
unsigned int line_width;
int line_style;
int cap_style;
int join_style;
>>SET need-gc-flush
>>ASSERTION Good A
A call to xname sets the 
.M line_width ,
.M line_style ,
.M cap_style
and
.M join_style
components of the specified GC to the values of the
.A line_width ,
.A line_style ,
.A cap_style
and
.A join_style
arguments.
>>STRATEGY

*Line_Width
Create a window.
Create a GC with line_width = 1, fg = WhitePixel, bg = BlackPixel.
Draw horizontal line from (0, 1) to (0, 2) using XDrawLine.
Verify pixel at 0, 2 is set to bg.
Set line_width component of GC to 2 with XSetLineAttributes.
Draw horizontal line from (0, 1) to (2, 1) using XDrawLine.
Verify pixel at 0, 2 is set to WhitePixel using XGetimage and XGetPixel.

*Line_Style
Create a window.
Create GC with line_style = LineDoubleDash, fg = WhitePixel, bg = BlackPixel, dashes = 1, fn = GXcopy.
Draw line from (0, 0) to (1, 0) with XDrawLines.
Draw dashed line using XDrawLine.
Verify pixel at (1, 0) is bg with XGetImage and XGetPixel
Set GC line_style component to LineSolid with XSetLineAttributes.
Redraw same line.
Verify pixel is set to bg.

*Cap_Style
Create a window.
Create GC with cap_style = CapButt, fg = WhitePixel, bg = BlackPixel, line_width = 0.
Draw lines from (0, 0) to (1, 0) using XDrawLines.
Verify pixel at (2, 0) is bg using XGetImage and XGetPixel.
Set cap_style component of GC to CapProjecting.
Draw line from (0, 0) to (1, 0) using XDrawLines.
Verify pixel at (2, 0) is fg using XGetImage and XGetPixel.

*Join_Style
Create a Window.
Create GC with line_width = 3, Join_style = JoinBevel, bg =BlackPixel, fg = WhitePixel, fn = GXxor.
Draw two joined lines (0, 1) , (2, 1) , (2, 3) using XDrawLines.
Verify Pixel at (0, 4) is bg using XGetImage and XGetPixel.
Set join_style component of GC to JoinMiter using XSetLineAttributes.
Draw two joined lines (0, 1) , (2, 1) , (2, 3) using XDrawLines.
Verify Pixel at (0, 4) is fg using XGetImage and XGetPixel.
