RFR: 6185110: Undefined behaviour of SampleModel for width, height < 0

[Phil Race]

The only significant change here is to ensure that all SampleModel types throw a specified exception if a client
calls any of the following methods with a negative width or height.
getPixels(..)
setPixels(..)
getSamples(..)
setSamples(..)

The rest is fixing the javadoc to properly describe what happens and some minor cleanup.
I use {@inheritDoc} to avoid repeating the super-class doc. And no one now has to tediously compare them.
I could just delete the javadoc but that would cause no javadoc to be generated for an overridden method.
There were a couple of surprises with {@inheritDoc} and the one I had to deal with is that declared RuntimeExceptions
are not inherited. You need to explicitly re-add them.

I added a test which verifies the behaviour for illegal arguments.

There will be a CSR.
