For below expression, the ascent becomes to upper.

Add workaround code to enlarge descent when y of first VListRow is negative.
This hide other bug (bounding box of frac seems too small) and we should fix correctly in the future.

Support multiline math for kotlitex side.

Change ascent calculation drasticaly. Now ascent is calculated based on the height of firstListRow bounding box.
Also fix debug bounding box rendering.
These change fixes #134 by side effect.
Also, this change contains workaround of #161.

Previous virtual height based rending was wrong because font metrics related calculation is based on real height.
So now just put real height to baseSize and keep ratio 1.0 for drawRenderNodes.
I'll remove ratio in the next change.
