title: In iOS, how do you get the current line width of a CGContext?
body: <p>There's a call <code>CGContextSetLineWidth</code>, but I don't see a corresponding <code>CGContextGetLineWidth</code> or even a <code>CGContextLineWidth</code>.  How can I get the current width set in the context?  I need to know what this is for my draw routines in a library.</p>
