• null
  Returns Surface without backing pixels. Drawing to crate::Canvas returned from Surface has no effect. Calling Surface::image_snapshot() on returned Surface returns None.
• raster
  Allocates raster Surface. crate::Canvas returned by Surface draws directly into pixels. Allocates and zeroes pixel memory. Pixel memory size is image_info.height() times row_bytes, or times image_info.min_row_bytes() if row_bytes is zero. Pixel memory is deleted when Surface is deleted.
• raster_n32_premul
  Allocates raster Surface. crate::Canvas returned by Surface draws directly into pixels. Allocates and zeroes pixel memory. Pixel memory size is height times width times four. Pixel memory is deleted when Surface is deleted.
• wrap_pixels
  Allocates raster Surface. crate::Canvas returned by Surface draws directly into pixels.
