• fix: massive memory leak after quit (#14)

Calling canvas.quit() would still continue the event loop...saturating the task buffer causing a leak.

• feat: load image surface (#16)

// png or jpeg
// for bitmap, use canvas.loadBitmap("player.bmp")
const surface = canvas.loadSurface("player.png");
const texture = canvas.createTextureFromSurface(surface);
