Enlightenment CVS committal
Author : xcomputerman
Project : e17
Module : libs/esmart
Dir : e17/libs/esmart/src/lib/esmart_trans_x11
Modified Files:
Esmart_Trans_X11.h esmart_trans_x11.c
Log Message:
Add more pseudo-transparency evilness (really only did this for demo
purposes) -- option for trans_x11 to do a screengrab instead of fetch
root pixmap. See http://xcomputerman.com/files/emotion_trans.png for
a sample of this.
