%
% Returns a flag to be passed to the 'specialFlags' optional argument of
% Screen('TransformTexture');
%
% The flag tells the command that the input texture(s) are already in a
% normalized upright format, regardless what the textures themselves claim.
% This allows to save on some internal format conversion overhead if the
% textures are really normalized, or if you can use some hacks in your code
% to at least fake that situation.
