LinePlot SetWeight & DrawLine

[dpde]

While using this library I ran into the issue that SetWeight on LinePlots doesn't work correctly.

While digging through this code I ran into this part here:

jpgraph/src/image/Image.php

Line 1565 in 0c5053e

// $this->DrawLine($this->img, $x1, $y1, $x2, $y2, $this->line_weight, $this->current_color);

Does someone remember why the function \imageline was used instead of \Amenadiel\JpGraph\Image\Image::DrawLine ?
It seems that DrawLine respects the configured weight correctly and imageline does not.

Btw: Nice commit message. I can feel the pain at night. ;-)
