<p class="MsoNormal"><span style="color:#1F497D">We actually mentioned fastuidraw while we were at the contributors meeting as a potential replacement for our Cairo rendering for PlayStation. When we got to a point with our port where we can start evaluating
we’d be interested in taking a look. The only problem I had with the setup was a reliance on boost, but maybe there are ways around it.<o:p></o:p></span></p>

<p class="MsoPlainText">Hi,<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I was directed here by some colleagues as this is the place to post the following to get started on the following proposal.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I have been working on an experimental 2D renderer that requires a GPU, the project is open sourced on github at
<span lang="FI"><a href="https://github.com/01org/fastuidraw"><span lang="EN-US">https://github.com/01org/fastuidraw</span></a></span>. I gave a talk at the X Developers Conference this year which can be seen from
<span lang="FI"><a href="https://www.x.org/wiki/Events/XDC2016/Program/rogovin_fast_ui_draw/"><span lang="EN-US">https://www.x.org/wiki/Events/XDC2016/Program/rogovin_fast_ui_draw/</span></a></span> .<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I made a benchmark which makes heavy use of rotations and clipping and ported to SKIA, Qt’s QPainter and Cairo. The benchmark and its ports are in the git repo linked above under the branch with_ports_of_painter-cells. It's performance
advantage of FastUIDraw against the other renderers was quite severe (against Cairo and Qt's QPainter over 9 times and against SKIA about 5 times faster).<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I would like to explore the option of using FastUIDraw to implement a WebCore::GraphicsContext backend for the purpose of making drawing faster and more efficient on Intel devices that are equipped with a GPU. I also think that some
minor modifications to WebKit’s use of GraphicsContext will also give some benefits. I have worked on WebKit a few years ago and knew/know my way around the rendering code very well (atleast at that time).<o:p></o:p></p>

<p class="MsoPlainText">Looking forward to collaboration,<o:p></o:p></p>
