I don't think so. OpenGL has well-defined rasterization semantics.
It ensures that there is neither overdraw (leading to visible
double-blending) nor gaps between adjacent primitives.
You might be referring to certain sub-pixel-sized triangles (multiple
triangles covering a single pixel). Here, it depends on the sub-pixel
rendering accuracy of the accelerator. But this is irrelevant if we talk
compositing which certainly uses primitives larger than a single pixel.
