X-Git-Tag: accepted/2.0/20130306.224007~63^2~19
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c4c1bf7273fdd93605e1818853a0542d8fa51a47;p=profile%2Fivi%2Fecore.git

Ecore_Evas (wayland): Implement alpha_set, transparent_set, and
ignore_events for ecore_evas_wayland_shm.

NB: I have to code for egl done, but am tracking a segfault when we
set alpha :/
