30593005:
IPC pickling optimizations for geometry types. (Closed)
DescriptionIPC pickling optimizations for geometry types.
Pass gfx::Transform, gfx::Size(F), gfx::Rect(F) and gfx::Vector2d(F) with a
single Write call to the pickler.

*RESULT mean_frame_serialization_time: DelegatedFrame_ManyRenderPasses_10000_100= 24118 us
This gives about a 2-3x improvement in time to serialize shared quad states and
render passes.
