* This option has always been a mixed bag - when originally written captures
weren't compressed at all so saving the cost of a initial contents on a
gbuffer would have a significant savings.
* Now with compression the savings are lesser, and it's a source of
bugs/confusion for the case where either a bug is caused by leaking data from
the previous frame or worse still the contents are discarded incorrectly.
* D3D11 will now behave as the other APIs will - saving initial contents
whenever needed even if they seem like they might not be used.
* Screenshots and icons are updated to latest style
* Many out-dated references and mentions of support updated.
* Documentation added for new windows like resource inspector and
performance counter viewer, as well as new features like saving
bookmarks, resource names.
* Added documentation for Android support as well as OpenGL ES support.
