Usage example:
//Solid Rectangle
auto shape = tvg::Shape::gen();
shape->appendRect(0, 0, 400, 400);
shape->fill(0, 0, 255);
//Mask
auto mask = tvg::Shape::gen();
mask->appendCircle(200, 200, 125, 125);
mask->fill(255, 255, 255); //AlphaMask RGB channels are unused.
//Nested Mask
auto nMask = tvg::Shape::gen();
nMask->appendCircle(220, 220, 125, 125);
nMask->fill(255, 255, 255); //AlphaMask RGB channels are unused.
mask->composite(std::move(nMask), tvg::CompositeMethod::AlphaMask);
shape->composite(std::move(mask), tvg::CompositeMethod::AlphaMask);
canvas->push(std::move(shape));
//Star
auto star = tvg::Shape::gen();
star->fill(80, 80, 80);
star->moveTo(599, 34);
star->lineTo(653, 143);
star->lineTo(774, 160);
star->lineTo(687, 244);
star->lineTo(707, 365);
star->lineTo(599, 309);
star->lineTo(497, 365);
star->lineTo(512, 245);
star->lineTo(426, 161);
star->lineTo(546, 143);
star->close();
star->strokeWidth(30);
star->strokeJoin(tvg::StrokeJoin::Miter);
star->strokeFill(255, 255, 255);
//Mask3
auto mask3 = tvg::Shape::gen();
mask3->appendCircle(600, 200, 125, 125);
mask3->fill(255, 255, 255); //AlphaMask RGB channels are unused.
mask3->opacity(200);
star->composite(std::move(mask3), tvg::CompositeMethod::AlphaMask);

auto shape1 = tvg::Shape::gen();
shape1->appendRect(0, 0, 200, 200); //x, y, w, h
shape1->appendRect(100, 100, 300, 300, 100, 100); //x, y, w, h, rx, ry
shape1->appendCircle(400, 400, 100, 100); //cx, cy, radiusW, radiusH
shape1->appendCircle(400, 500, 170, 100); //cx, cy, radiusW, radiusH
shape1->fill(255, 255, 0); //r, g, b
shape1->opacity(128) //opacity
