Paints text at the specified location. This will not attempt to render the text as html nor will it offset by the insets of the component.

param
ss SynthContext
param
g Graphics used to render string in.
param
text Text to render
param
bounds Bounds of the text to be drawn.
param
mnemonicIndex Index to draw string at.
