[Feature Request] Make FreeSerif the default font for Math

I’ve played a bit with Math equations. I changed the Metadata of the standard Ubuntu font ‘FreeSerif’ to OpenSymbol and replaced it with opens___.ttf.

The cool thing about is, that it is much prettier than the new OpenSymbol font and it is a Unicode font, and has plenty of math symbols (like double-stroke letters, frankatur, calligraphy, and many many symbols).

Since the new OpenSymbol font uses standard Unicode, it can be replaced smoothly. I’d recommend to replace OpenSymbol with FreeSerif and enhance the catalogue of Math with e.g. double-stroke letters, frankatur, calligraphy, and many symbols.

Also the appearance is really smooth if you use FreeSerif as your default font for the entire document.

FreeSerif is not currently distributed with LO so it is not possible to make it the default font for anything as it may not be present on the system of the user. This AskLO thread provides a list of fonts shipped with LO under v3.6 and v4.0. I am not certain but I would think that FreeSerif being a GPL licensed font would make it incompatible with the less restrictive LGPL that LO is distributed under.
