x11proto-present-dev 1.0-1 (i386 binary) in ubuntu trusty

 This package provides development headers describing the wire protocol
 for the Present extension, which provides a way for applications to update
 their window contents from a pixmap in a well defined fashion, synchronizing
 with the display refresh and potentially using a more efficient
 mechanism than copying the contents of the source pixmap.
