+Consecutive raster draws now merged
+-----------------------------------
+
+Elements of a vector output can be individually set to rasterized, using
+the `rasterized` keyword, or `set_rasterized()`. This can be useful to
+reduce file sizes. For figures with multiple raster elements they are now
+automatically merged into a smaller number of bitmaps where this will not
+effect the visual output. For cases with many elements this can result in
+significantly smaller file sizes.
+
+To ensure this happens do not place vector elements between raster ones.
