    new usable functionalities. All together it can make the graphical 
    interface a more hospitable as well as efficient environment for the user.
  
!   In order to use these features, powerful 2D graphics engines have been 
!   developed to carry out these tasks by utilizing the acceleration capabilities 
!   in modern graphics hardware. 
  
!   This project aims to investigate the possibilities for creation of an 
!   open source 2D graphics library that can be used to render hardware 
!   accelerated graphics. An analysis will also be made to tell wether the level 
!   of hardware acceleration provided by the X Window System~\cite{x} can be 
!   improved by using this library for rendering.
  
    Hopefully the work presented in this paper will be useful in the design of
    a new generation of hardware accelerated graphic applications in the X 
    Window System and the open source community in general.
- 
-   The current implementation of this library shows speedups of 8X to 240X 
-   compared to traditional rendering models on some of the benchmark tests.

+   Unfortunately these features demand a lot of computation time from the CPU. 
+   In the past this has meant a slowdown throughout the entire system as well as 
+   a significant limitation in the kind of visual effects that can be used.
  
!   This is why many proprietary window systems have developed
!   powerful 2D graphics engines to carry out these tasks by utilizing the 
!   acceleration capabilities in modern graphics hardware. 
  
!   This project investigates the potential usefulness of an open source
!   implementation of such a graphics engine. We present \libname, 
!   a portable open source 2D graphics library that can 
!   be used to render hardware accelerated graphics.
! 
!   A special analysis has been made to investigate wether the level of 
!   hardware acceleration provided by the X Window System~\cite{x} can be 
!   improved by using \libname to carry out its fundamental drawing operations.
  
    Hopefully the work presented in this paper will be useful in the design of
    a new generation of hardware accelerated graphic applications in the X 
    Window System and the open source community in general.
