Didn't someone mention months ago that this is a known gmail problem and is 
going to be fixed? Anyway, IIRC there's a setting to work-around this 
problem. Another gmail user certainly can tell you.

There're several reasons why Stephan designed HVIF in the first place. And 
that was not because of a single feature SVG misses (I actually wouldn't be 
surprised, if SVG does already support the particular feature you mentioned). 
HVIF is geared to icons. It beats even compressed SVG in size by a 
significant factor (which is of relevance since the icon ends up in BFS 
attribute) and has several features that allow the designer to make even a 
small icon look crisp. I'm no expert in this area, but I'm sure Stephan, 
who's still traveling for another month, will happily explain it to you in 
greater detail when he's back.

It will be (or even is -- I haven't tested it yet) quite easy: Right click 
the file -> Add-Ons -> File Type -> double click the icon to bring up 
Icon-O-Matic -> import the SVG icon -> save -> done.
