SkPicture records on the compositor thread get turned into bitmaps on the GPU in one of two ways: either painted by Skia's software rasterizer into a bitmap and uploaded to the GPU as a texture, or painted by Skia's OpenGL backend (Ganesh) directly into textures on the GPU. Does Skia: make a quad (using 2 triangles) and paint the circle on top of it using auto generated shaders? Or, makes hundreds of triangles and arrange them into a fan?
