OK, sounds like you're being affected by the text matrix. In CG, there are 3 font properties that determine the font rendering: font name, font size, and text matrix. You need to manage all 3.
The easiest approach is to use -[NSFont setInContext:] to let the Cocoa object set all 3 properties for you. Another approach is to reset the text matrix directly using CGContextSetTextMatrix. Note that the translation part (tx and ty components) are directly tied to the text position (CGContextSetTextPosition). You need to reset the text matrix before calling CGContextSetTextPosition, or you could just update the text position using CGContextSetTextMatrix.
