drawLine() ignores line width with GD <= 2.1.0 #1304
Description
Describe the bug
I am using Image v3.4.0 , I used drawLine to draw lines, it has always been 1px
The same result was obtained using the DrawPixelLine of #1298
Code Example
$image->drawLine(function (LineFactory $line)use($listHeight) {
$line->from(980, 20); // starting point of line
$line->to(980, $listHeight-20); // ending point
$line->color('#723e4b'); // color of line
$line->width(5); // line width in pixels
});

This is a really strange error that I can't really explain at the moment.
As described in #1298 and here, the width is apparently discarded when
imageantialias()is activated. A workaround could be to use a custom modifier that works without the function but of course also has the disadvantage that the line is not antialiased. How this could work I already described here.However, I am still wondering, because in my environment, I have no problems and everything works as expected. I can explain this by the fact that the bug was fixed at some point. I see that you are using GD version
bundled (2.1.0 compatible).I am currently running
GD 2.3.3, maybe you can try to switch to this newer version as well.My Environment

On linux, using gd 2.3.3 is possible , But in window the default gd version is 2.1.0
