Commit cd1631b17dd0 fails to scale the global_font_size by UI scale in
BLF_set_default. Generally used for simple text output like statistics.

For simple text output we can call BLF_set_default to initialize the default font with a default size. Unfortunately I forgot to scale this by UI scale. BLF_draw_default works fine; It is only if you call BLF_set_default followed by regular font draws.

In this capture by @Guido (Nurb2Kea) you can see both some informational text too small and statistics with incorrect alignment and spacing, when the UI scale is 2X:

Will commit without review as this is very recent own code.
