GlyphWarmerImpl's Picture is not drawn on View?

In GlyphWarmerImpl, the textlayout is drawn to a Picture on separate thread, however it seems this Picture is not used, and not drawn on the real view?

this is intentional to warm the font cache - from the documentation:

On 4.0+ devices, TextLayoutBuilder can warm up the FreeType font cache. By drawing these glyphs on a background thread onto a Picture, TextLayoutBuilder warms these glyphs and can help reduce their render time.

also, if you want to disable this behavior, you can leave out the setGlyphWarmer call on your builder.
