Subject: Stub functions for Wayland usage
X-Git-Tag: accepted/2.0alpha-wayland/20121219.185853~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a6c48885d463efd6a773b1d40f076fe22c3d30a8;p=profile%2Fivi%2Fecore.git

Stub functions for Wayland usage

Some functions called by applications make direct calls to X. This will
make apps crashing if Wayland is being used. As a hot fix, stub functions
making calls to X by checking DISPLAY environment variable and
returning to caller if DISPLAY is not set.
