Patches for weston1.9 in linux BSP 4.1.15_1.1.0 and 4.1.15_2.0.0 are different.In L4.1.15_2.0.0, it added the following patches for westion1.9. And what these patches do is to use G2D API to replace Gal2D API.
1)G2D uses CPU to render and Gal2d uses GPU2D to render, is it right?
2)Comments of the 0009 patcth says 'Fix the errors in multi display mode.', so could you tell me what errors are fixed by these patches?
3)Can I apply these patches to L4.1.15_1.2.0 directly? Or need to do something else(If yes, what should I do?).
