attempt to make tensorboard graph svg text redable when using a minimum-font-size in firefox

tf-graph-scene.css

/* intended to be used with stylus (user-css add-on) or similar
** no copyright intended
**
** Basically the problem is that I use a minimum font size in firefox to ensure
** sites can't set fonts smaller than I can read.  Zooming the sites is not an
** acceptable option because it also jacks up the layout.  minimum font size
** works nearly everywhere except for single edge cases like tensorboard's SVG
** text ... and I can't think of a single other example at the moment.
**
** update:
**
** There's nolonger any way to fix the stupid font layouts in tensorboard graph
** svg; at some point (prolly near tensorflow 2.0), tensorboard seems to be
** dropping every child element in a Shadow DOM (e.g., :host, ::part,
** #shadow-root, etc) short of using "* { font-size-adjust: 0.2; }" You'll never
** get this to work.
