wg_engine: introduced composition ability
[issues 1479: Masking](#1479) Supported composition methods: AlphaMask InvAlphaMask LumaMask InvLumaMask AddMask SubtractMask IntersectMask DifferenceMask 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); if (canvas->push(std::move(star)) != tvg::Result::Success) return;
