Dear Enlightenment Users, 

I am very new to Elementary, still reading through the examples and learning 
the various features. 

I could use a bit of assistance in getting started towards accomplishing my 
goals. 

Here is what I would like to do: 

1. Create an a program that uses Elementary for event loop, widgets and 
graphics 
2. Render the graphics to an in-memory buffer 
3. Receive a notification or callback each time the buffer changes, and send 
the buffer contents to an external device or program (e.g. via a socket or 
pipe) 

This program would eventually run on a Linux system without a display, so there 
is no framebuffer or graphics hardware available. For now I would run it on a 
desktop Ubuntu 15.10 system and send the buffer contents via IPC to a separate 
program for viewing the contents. 

Based on initial reading of the code, the function elm_win_fake_add() looks 
like it may help, but the warnings in elm_win_legacy.h might imply otherwise. 

I would be grateful for any hints to help get started. 

Thank you and best wishes, 
Markus
