Always render frozen columns and filter rendering for non-frozen columns

[ronnykarlsson]

There was a bug which caused frozen columns cell content to disappear when the non-frozen viewport was too wide and scrolled to the right, content then disappears when scrolling up and down in the grid.

Inside the getRenderedRange function it would calculate incorrect viewport dimensions and filter out frozen columns that were visible. I've updated that bit so it'll render a viewport for what's in the right non-frozen part of the grid and then everything that's frozen for the left viewport.

Hi @ronnykarlsson! Sorry for my delay.

Thanks for your contribution. Could you add an example that shows this bug?

[ronnykarlsson]

For an example, look at example-frozen-columns.html (http://jlynch7.github.io/SlickGrid/examples/example-frozen-columns.html) and do this:

1. Set the width of the grid to 400px. $('#myGrid').css('width', '400px')
2. Set frozen column to 1
3. Scroll the grid to the right
4. Scroll down - now the Title-column will be empty.

This bug is produced when the non-frozen width is greater than the grid width.
