Subject: Bug: Latex preview overlay scaling not consistent across PPI

The size of the latex preview overlay scaling is inconsistent across
screens with different pixel densities.
I've set my customization to use dvipng for the latex previews I see when I
type C-c C-x C-l. Dvipng is customized as follows:
[image: Inline image 1]
The "Value" is set to (1.0 . 1.0), which I would think means that the font
size in the preview overlay is scaled the same as the font size org
buffer's normal text.
This is more or less true for a Windows 7 machine connected to a 24",
1920x1080 pixel monitor:

However, on a Windows 10 machine with a 12.3", 2736x1824 pixel monitor, the
same customization looks like this:
[image: Inline image 3]
On the second computer (a Surface Pro 4) the previews are tiny because the
screen has a much higher pixel density; the normal text is scaled
appropriately but the overlays aren't scaled to match.
I'd like keep the same .emacs file across all the machines I have to use,
so it would be best if the preview scaling was consistent.
Possibly the overlay scaling calculation is done using the function
window-text-width without the *pixelwise *argument, which would return a
width in characters. To avoid changing the calculation too much, you could
use window-max-chars-per-line, which considers font size and some things
that would be missed by window-text-width even if *pixelwise* was used.
