Get/set the font style for future text draws in this window. Useful values for
style follow; they may be OR'd. See Inside Mac
TextFace() for more. On
M$-Windows and GNU/Linux, only a subset of these settings is honored - All
settings are accepted, but some of them are silently ignored on Windows and
Linux. On Windows the default text style is bold, because this increases
readability on that system.
0=normal,1=bold,2=italic,4=underline,8=outline,32=condense,64=extend.
You can assign a default font style for new windows via a call to
Screen('
Preference', '
DefaultFontStyle'). The initial default font style is
operating system dependent.
Not all fonts support all style settings. Unsupported settings for the currently
selected font will be silently ignored.
