[GRASS translations] 5.7: Multibyte/Freetype support added to XDRIVER

[Markus Neteler]

Hi,

based on 5.0-i18N I have merged the relevant changes
for Multibyte/Freetype support into the display system.

I am not sure if it works, as the new d.font.freetype (for
font selection) stops at one point. Maybe it needs 
updates for Freetype2?

The HTML page of d.font.freetype explains how it has
to be used, it should work for any Freetype font,
it was developed in particular for Japanese/Vietnamese/Chinese.

Assistance welcome...

 Markus
