#include "nsMathMLmsqrtFrame.h"

// <msqrt> -- form a radical - implementation

//  The code assumes that TeX fonts are picked.
//  There is no fall-back to draw the branches of the sqrt explicitly
//  in the case where TeX fonts are not there. In general, there are no
//  fall-back(s) in MathML when some (freely-downloadable) fonts are missing.
//  Otherwise, this will add much work and unnecessary complexity to the core
//  MathML  engine. Assuming that authors have the free fonts is part of the
//  deal. We are not responsible for cases of misconfigurations out there.
