| 11 // | |
| 12 | |
| 13 //NOTE: | |
| 14 // The code assumes that TeX fonts are picked. | |
| 15 // There is no fall-back to draw the branches of the sqrt explicitly | |
| 16 // in the case where TeX fonts are not there. In general, there are no | |
| 17 // fall-back(s) in MathML when some (freely-downloadable) fonts are missing. | |
| 18 // Otherwise, this will add much work and unnecessary complexity to the core | |
| 19 // MathML engine. Assuming that authors have the free fonts is part of the | |
| 20 // deal. We are not responsible for cases of misconfigurations out there. | |
