In addition to the already handled processed formats and sizes, this patch adds handling of raw formats and sizes, which correspond to the capture formats and sizes. Raw and processed formats are handled separately. The intention is that in case both raw and processed formats are requested then the raw formats should be left intact to the extent possible and not be influenced by the processed formats (implying that raw parameters compatible with the processed output requirements must be requested by the application). Accompanying checks for invalid role specifications are introduced. This is another preparatory patch without making raw outputs working.
