[rrd-developers] [patch] [SVG] Support for CSS font families.

[Tobias Oetiker]

Hi Alex,

thanks for your patch ... but, before you invest any further time
in altering 1.2.x please take a look at the svn trunk of rrdtool
development for 1.3 has started in earnest ...

regarding graphics, we will switch to cairo with 1.3 cairo comes
with its own svg support, so you may to the check cairo svg out
maybe this will solve all the problems you have with the curent
version (once it is implemented) ...

the same is true for pdf output, which will follow png output to
the point including support for truetype fonts and such ...

good things ahead ...

cheers
tobi
