Subject: Add possible capabilities CURSOR_PLANE and ARBITRARY_MODE
X-Git-Tag: upstream/0.1.8~330
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9fc71519912c33a270f2579e1ef52b809faf130e;p=profile%2Fivi%2Fweston-ivi-shell.git

Add possible capabilities CURSOR_PLANE and ARBITRARY_MODE

The CURSOR_PLANE capability indicates that the backend has a concept of a
cursor plane and can handle a cursor without compositing.  This is currently
only advertised by the DRM backend.

The ARBITRARY_MODE flag specifies that the backend is capable of switching to
virtually any resolution.  This is currently only advertised in the RDP
backend.  While it's a bit buggy right now, it should be capable of this.
