Psychtoolbox>Screen.{mex*} subfunction

textModes = Screen(‘TextModes’);

Return a cell array of strings naming allowable text modes for
Screen(‘TextMode’).
Please note that none of these modes are supported in the current Psychtoolbox,
except on OSX with its default text renderer 1 aka the Apple CoreText renderer,
so whatever ‘TextMode’ you set will be silently ignored and have no effect.
