[LON-CAPA-users] uploading SVG

Use of SVG image files requires modification to the mime.types file on  
your web server (and web server reload).

The mime.types file shipped with LON-CAPA releases has not, up until  
now, included the required line:

image/svg+xml  svg svgz

because of LON-CAPA policy to support older browsers (i.e., Internet  
Explorer 8 and older). Note: use of SVG with IE8 requires an SVG  
viewer on the client side.

Anyway, I have committed an updated mime.types file to the LON-CAPA  
CVS repository, and will include that in the forthcoming 2.11.1


To use LON-CAPA's mime.types config file, your domain's Apache  
server's configuration needs to include:

TypesConfig conf/mime.types

Currently, printout generation (i.e., use of LON-CAPA's Print function  
to generate a PDF from TeX) will fail if you include an svg file in an  
img tag in a LON-CAPA resource.  See:
