[MapServer-dev] Global Font Scaling

[Scott]

Hey Seth,

SYMBOLSCALEDENOM. Yep, that's it.

I've been using mapserver for years and that went completely under my radar.

In many cases I use an attribute to set the font size, when an SQL query 
is involved, never with an expression. Otherwise, size is hard-coded.

Thank you!
Scott
