UICollectionViewCell Height Bug

=========================

This demo project demonstrates the UICollectionViewCell's bug when the height of the 1st cell in 1st section is 0.0.

The bug occurs with the following setup:

* the UICollectionsView has 2 sections

* The 1st section has one row

* The 1st row has a height of 0.0

## Actual result

* The cells (in bounds) are NOT visible, but the collectionView can be scrolled, looks like that the cells are hidden

## Expected Result

* All cells with a height > 0 should be visible.

## Example

* Download demo project

* Toggle the schemes ShowBug, UseWorkaround

Give the 1st section's row a minimum height of 0.1f
