[Kst] Kst 2.0.4: Request to set DPI Resolution for PDF Export

[Barth Netterfield]

Thanks!  The legend font resolution problem is clear in the code.  I
submitted a bug report.  It will be fixed for 2.0.5.

If that were fixed, so legend text was rendered directly to the
printer, like it is for everything else, would there be a need for (1)
and (2)?

This is unlike the other labels which get aparrently encoded as true type outline characters and thus rendered at full resolution.

According to the qt docs the alternative is "::HighResolution" which is 1200dpi, which really is no alternative either because it requires enormous amounts of memory for plotting. Therefore I would like to request 2 two things:
