Subject: [PATCH 1/2] backend-drm: disable "bo geometry out of bounds" message
The message was being printed repeatedly whilst running an opaque
windowed application, because the application wasn't within the
framebuffer dimension limits.

Subject: [PATCH 3/3] libweston: reduce checks for dmabufs with DRM modifiers
If the buffer associated with a dmabuf has a DRM modifier, then
checking the stride and stride*height against the size of the
dambuf may not make sense, so skip the check.
IMG lossy framebuffers have a smaller size than that of the
equivalent linear framebuffer.
