Admittedly a subtlety, but it would be great if Processing could have text() return the pixel width of the text it just rendered. I often find myself trying to put some text after other text, but with a different style so it has to be a separate text() call:

THIS IS THE TITLE  and this is the subtitle

requires me to do something like
Code:

textFont( titleFont );
text( title, 100, 100 );
float subTitleOffset = textWidth( title + "  " );
textFont( subtitleFont );
text( subTitle, subTitleOffset, 100 );
 

It would be sweeter if I could simply:
Code:

textFont( titleFont );
float subTitleOffset = text( title + "  ", 100, 100 );
textFont( subtitleFont );
text( subTitle, subTitleOffset, 100 );
 

I'm sure there would be other uses as well.

at least for now, if you use the text() command with no x and y coordinates, it will draw the text immediately after the last text drawn.

but i'm not sure if that api feature will stay in. having text() return the width sounds like a better option, rather than keeping track of internal state (though this doesn't keep track of the y coordinate of the text...)
