Make the fields of `TextMetrics` lazily calculated, and add an API that eliminates double layouts. #408

Closed pcwalton closed 4 years ago

pcwalton commented 4 years ago

This adds an extension to the HTML canvas API that allows you to pass the TextMetrics object returned by measure_text() to fill_text() and/or stroke_text() to draw the measured text without laying it out again. It improves performance on the canvas_nanovg demo.
