WebRender is an experimental GPU accelerated rendering backend for Servo.
The WebRender backend can be specified by running Servo with the -w option (otherwise the default rendering backend will be used).
WebRender has many bugs, and missing features - but it is usable to browse most websites - please report any WebRender specific rendering bugs you encounter!
Hopefully the build machines and everyone using Servo has GL 3.3 available on their machines - if it causes any problems, we can revert this change and investigate further.
I was going to implement Uniform4fv with sequences, (since it
practically implemented), but we can't until we support Float32Array
args because codegen doesn't know how tu differenciate between both.
