[Xcb] XCBSync and XCBFlush

[Vincent Torri]

Hello,

XCBSync is now deprecated in xcb. So now, I need to change a bit the code
of the xcb evas engine. But how ??

Now, it seems that I have 2 solutions:

1) remove XCBSync
2) use XCBFlush instead

My questions are:

1) When is it possible to remove XCBSync. Is it only 'a posteriori' ?
2) If i can't remove XCBSync, is using XCBFlush always sufficient ?
3) Is there any good doc about the differences of these 2 functions ?

thank you

Vincent
