[why] Overlay won't move to a new positon if viewport size is smaller than what can be handled. It'd either disappear or stay at the old position. This condition is for example hit if overlay is moved too much outside of left or top edge of the screen, but it applies to any non-cursor plane type. [how] Reject this contidion at validation time. This gives the calling level a chance to handle this gracefully and avoid inconsistent behaivor.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
