Thank, Guillaume Piolat.

I using CPU Pentium B970 It is old CPU, but even it contains a 
graphics accelerator.
Mesa DRI Intel(R) HD Graphics 2000 (SNB GT1), has 4 conveers on 
GPU.
Smartphones also contains GPU.
Because OpenGL has high priority.

CPU render, may be later.

Thanks, I noticed turtle, dg2d. It has clipping, it usefull.
What about text rendering ?
