[cairo] [PATCH 46/72] drm: generalized framebuffer-based surface operations
Enrico Weigelt, metux IT consult
enrico.weigelt at gr13.net
Tue Dec 29 01:17:24 PST 2015
Several driver specific backend functions just proxy to the underlying
image surface, which then renders directly into the framebuffer.
These functions dont need t be driver specific and thus can be generalized.
