I have some clarification in cairo gl and i am currently using my webkit based on directfb but now i am moving to cairo opengl.
Herewith we have faced a drawing in current focus region only and we are using cairo-gl(1.14.2). we have created a eglCreateWindowSurface and utilized as two cairo egl surface for front surface and another for back surface.
But we can draw only in united region only.
So please suggest us whether any texture concept need to implement.
Note: FYI, We have checked the gltexImage2D but we cant take the surface data for gltexImage2D.
And for this answer i will provide just 250 INR only. If you are ok, just ping me
