I was wondering if WebGL is considered stable enough to be enabled by default. It makes some PDFs render much faster and it has been off by default for a while now, so we have had quite some time to test it.

If we decide to enable WebGL by default, we should not forget to update https://github.com/mozilla/pdf.js/blob/master/extensions/chromium/preferences_schema.json#L39 as well.

if (this.operatorList.lastChunk) {
          this.gfx.endDrawing();
          if (this._canvas) {
            canvasInRendering.delete(this._canvas);
          }
          this.callback();
        }
      }
    }
  }
  return InternalRenderTask;
})();
