Fixed a couple of subtle bounding box vertical positioning issues relating to text baseline alignment.

Browse Source 
The issue would generally manifest when laying out multiple items on a same line, with varying heights and text baseline offsets. (#2833)
Some specific examples, e.g. a button with regular frame padding followed by another item with a multi-line label and no frame padding, such as: multi-line text, small button, tree node item, etc. The second item was correctly offset to match text baseline, and would interact/display correctly,but it wouldn't push the contents area boundary low enough.
Note: previously the second parameter to ItemSize() was 0.0f was default, now -1.0f to signify "no text baseline offset request". If you have code using ItemSize() with an hardcoded zero you may need to change it. (+1 squashed commits)
