The trap for LATEX convertors

This file contains absolutely legal and ordinary (thought somevhere miningless) mathematical constructions in LATEX text to facilitate visual detection of image alignement algorithm flaws in LATEX to HTML convertion.

Lines alignement problem

The problem comes with the large height and (or) depth formulae. Usually such a formula as $x_s^{\int\limits_a^{N^1}\, dx}$ for example has larger height, then depth and there may be inproper large gap (vskip) before the next line. The situation of equal height and width $\left(x_s^{\int\limits_a^{N^1}\, dx}\right)$ is more controllable, as far as we do not try to get images scaled togater with text changing. The other most rare and very hard to resolve situation is a formula with a large depth, but a very small height: $y=1-\dfrac{\alpha}{1-\dfrac{2}{3-\dfrac{4}{5-x}}}$. I will appreciate any idea to keep proper interline distance in such a case without additional vskip over this formula thought suppoce it to be impossible: I failed to find a hint in html specifications how to force browser to leave a proper place lower image witout extra gup over it.

Inline alignement problems

The simple convertion algorithm can fail in the two reasons: The second is not a font bugs, it is a basic TEX feature, Convertion algorithm designer hate it, but have absolutely no chance to change it generaly and therefore he can not trust LATEX box dimentions.

All dots in the line are to be exactly alighned for any browser and selected text size.
