Where the OOo MinGW people get their __SEHandler from, no idea.

Don't use backslashes. Use correct case in header names.

This function matches up with GetFirstEntryInView, and will be useful
in saving the scroll state of a SvTreeListBox, in particular
the CustomAnimationList.

Scrolls the listbox so the given entry is the first visible entry.
The existing MakeVisible is not good enough since it won't scroll
down if the given entry is already visible.

The previous solution was giving somehow acceptable results
in the majority of cases, but was pretty broken
with corner cases where the arc is exactly half of the whole ellipse and where
the large arc flag is largely irrelevant.
If the sweep flag is equal to 0 drawing goes in the sense of decreasing angles.
If it is set, drawing goes in the sense of increasing angles.

The UNX code compiles fine both with MSVC and MinGW. In fact, the
non-UNX code did not compile with a modern MinGW.
