Saving PDF of (some) maps yields a low-resolution unusable PDF

Reported by koso...@gmail.com, Aug 9 2017 
UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.115 Safari/537.36

Steps to reproduce the problem:
1. In Chrome, go to https://www.google.fr/maps/dir/Laugardalsholl+Sport+Center,+Engjavegur,+Reykjav%C3%ADk,+Iceland/Leifsgata,+101+Reykjav%C3%ADk,+Iceland/@64.1380109,-21.9008571,14z/data=!4m13!4m12!1m5!1m1!1s0x48d674be2b114ee9:0xa2418dfee7b696a4!2m2!1d-21.8767213!2d64.1401852!1m5!1m1!1s0x48d674cb191ce11f:0xa7877e866f097f94!2m2!1d-21.9236389!2d64.1396549?hl=en&authuser=0
2. Print using the Chrome drop-down menu
3. 

What is the expected behavior?
A usable, print-resolution map.  In many cases, jiggling the "Scale" setting will fix the problem; in this particular case, it doesn't.

What went wrong?
The map is too low-resolution to be useful: street names are unreadable.

Did this work before? N/A

We can't reproduce this either, but seeing the low resolution PDF is created by Skia, maybe Hal has some insight into why it's the way it is.

Comment 4 by halcanary@google.com, Aug 23 2017 

(I'm on leave and won't be able to look into this in any detail.)

If you have a color-filter or image-filter applied to the image, it will get re-rasterized at SK_ScalarDefaultRasterDPI.

If the image is a SVG and has no filters, you'll get vector graphics out.

Comment 5 by thestig@chromium.org, Oct 25 2017 

So one question is, are there any Chrome extensions installed that may have affected the rendering output?

Comment 6 by thestig@chromium.org, Nov 14 2017 

Bug reporter: Can you try turning off any Chrome extensions you may have and see if that makes a difference? Maybe try asking a friend to print to PDF on a different computer and see if they can reproduce the problem as well.

We never heard back, so archiving this bug for now since we can't reproduce it.
