A TeX component comes to Powpress

Now you can use TeX components in Powpress to write mathematical expressions. To use this feature:

1. Click the "TeX" button to insert a TeX editor block
2. Type in a TeX expression
3. Save

To check out the supported functions, please check the manual here. Here are some examples:

\begin{aligned}
\nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\   
\nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
\nabla \cdot \vec{\mathbf{B}} & = 0 \end{aligned}
