This is a fix for a problem that happened (in "stock" wwwBASIC and all previous versions of BAM) when drawing lines with the LINE and the DRAW statements.

In certain circumstances, some of a line's pixels would be misplaced, causing gaps in a line. (See the images further below.)

This new version of BAM fixes the problem.

The before and after in images

The test program used to investigate and resolve the bug:

The problem is apparent in the left-side image (results from previous version of BAM). We can see two lines with gaps because of misplaced pixels.

The right-side image shows the results of the same program: no more gaps from misplaced pixels.
