    From the benchmarks made in the context of this project (see table 1, section 5)
    the amount of accelerated rendering achieved by Render doesn't seem to be enough
!   for the complex visual effects addressed by this project. This perticular benchmark
    is run on a Nvidia system but similar results were attained with Matrox drivers, 
    which have been known for having the best acceleration support for Render in the past.

    So the library developed in this project should clearly be designed to act as an 
    additional backend for Cairo providing this hardware accelerated output. 
+   Figure 1 illustrates these ideas by showing the the layers of software 
+   involved when an end application uses Cairo to draw accelerated output with GLX.
+   These layers are more described in subsequent sections.

    Still the question remains about how to actually render all the graphics

    Figure 1 shows output from cairo-demo using xrender and figure 2 shows the 
    corresponding output using the GL backend for rendering.

    area of continuous development. For example in the near future new functions
    for the creation and compositing of glyph sets probably need to be added for
!   more efficient rendering of text.
  
    Special functions for more efficient rendering of gradients could also be
    added at some level.
