Hello,

According to SVG specifications[1] and freedesktop's mime database[2],
the compressed .svg files should be named *.svgz (but not .svg.gz)

Please, support opening .svgz files locally (i.e from file:// ).

Thanks,

Franklin

>    <glob pattern="*.svgz"/>
>  </mime-type>

Reproducible: Always

Steps to Reproduce:
1. drag and drop an .svgz file on Firefox window
  (an .svgz file is an .svg file, compressed with gzip [then renamed]. More 
  and more tools generate compressed .svg files)

Actual Results:  
Firefox shows a popup window asking which program to use to open the file

Expected Results:  
Actually show the image, like if does if you drag and drop an .svg file.

.svg is a great open standard.
-> .svgz is even better (i.e smaller)!

According to bug 308153 comment 1, it should be supported if the webserver uses the correct headers. But this doesn't use a webserver, it reads the files directly. But it's not related to the Content-Type header (or MIME type), but on the Content-Encoding header !
