OpenGL and OpenCL support

[Ezio]

done googling, some stuff might be wrong

we already used MSAA as our FSAA \o/
newer implementation was CSAA/EQAA, there were other implementation like FXAA to make MSAA better or faster or both, and SMAA which better than FXAA

and here lies my first CSAA problem.

Code: Select all

if (fsaa)
	{
		SDL_GL_SetAttribute(SDL_GL_MULTISAMPLEBUFFERS, 1);
		SDL_GL_SetAttribute(SDL_GL_MULTISAMPLESAMPLES, fsaa);
	}

SDL dont have opengl extension that i need. i'm not sure if i call glEnable() would fix issue.we need new backend
what Per said can be done too, forcing from nvidia CP can do trick but difference would hardly seen unless you play on ultra hd tv or something
