Fix for HyperTreeList connector lines

wxPython Users
1

I was testing a new program where I use TR_HAS_VARIABLE_ROW_HEIGHT and I saw that the connector lines were wrong.

I hacked the a little bit and from my tests they look better

In my change, instead of making calculations of next position, I take the child mid height and draw up to the parent

Also I removed some lines that looked unnecessary (commented out the whole part)

Tested both in Windows XP and Ubuntu 9.04, python 2.6 (2.5 in win), wx 2.8.10.1

From my tests there’s no performance/flicker difference when drawing many items
