Text::_setCaptionHorizontal bug

I found a bug in Text::_setCaptionHorizontal which leads to a lot of crashes in my project (another past-the-end-iteration problem).

Here is a quick patch, which fixes the crashes:

It could use some more testing, especially regarding multi-line text display.

P.S.: The patch contains some lines, which only remove spaces or tabs from empty lines or the end of a line. This is pretty inconvenient. Could we agree upon configuring our editors to remove this stuff automatically, when working on QuickGUI?

Thanks for the patch. Why is it that we need to remove spaces or tabs at the end of lines? Imagine the scenario where you have a text box or label area in a window, and you can resize the window. We would be adding and removing the whitespace quads at runtime, which can get complex.

No, I mean in the source code. My editor is doing that automatically. So even if I barely change a file, tons of changes are produced, each only removing a few spaces.

Ah. I don't know how to tell Visual Studio to remove all trailing spaces/tabs, but I'll see what google gives me.

I couldn't find how to remove trailing whitespace, but it wasn't much of a burden for me.

I applied the patch, but I'm not at a point where I can commit. I will be in the next commit.
