Use DPI scaling to scale drawn fonts.

[gbburkhardt]

This fixes the scaling of fonts that are drawn to a GLCanvas or GLPanel. Previously, drawn text was the same size regardless of DPI scaling setting.

Thank you @gbburkhardt
Even though I use Graph w/ our own font rendering + GraphUI these days (see blogs https://jausoft.com/blog/tag/graph_type_rendering/) .. this shall help whoever still uses the old AWT resolution dependent rendering solution.
Great catch!
