Just because it can be enabled does not mean it should be unconditionally 
enabled. If building for an environment where, e.g., flash memory is scarce, 
every byte counts. Keeping the packageconfig and leaving it enabled by 
default will give the same result, but for someone trying to remove anything 
they do not need, it is then more obvious that the jpeg dependency is 
optional and can be removed if wanted.

Same here as for zlib.

> * libpng is a dependency, and is part of oe-core, so add it to DEPENDS

This too is optional and should have a packageconfig (which can be 
enabled by default since it is pulled in anyway due to other dependencies).

You also add dependencies on libgudev and libdrm, without mentioning it here.
Why is this? They too are optional, and they have not been needed before. 
If you want to add support for them, then do so by adding packageconfigs 
(which I don't think should be enabled by default to maintain the 
configuration as it was).
