I request that the various Symbology size settings have a precision to at least 4 places to the right of the decimal point, especially the Line width.

Here is why: with only 0.01 precision for Outline width it is impossible to render lines on screen that are exactly one pixel, for example. There will be gaps or two pixel width short segments quite often, which are especially noticeable on straight lines.

I believe that this behavior could cause some annoyance to many users (it annoys me because I can't set a better value that I know would work) and probably complaints.

I know that when a map is rendered to a high resolution printer the precision of the size doesn't make much difference in the result, but it does affect low resolution devices like computer displays.

I have found that a value of approximately 0.26458 for Outline width results in almost no gapping on a typical Windows computer. This may vary depending on platform.
