For the Page Thumbnails sidebar, Reader currently provides onInitThumbnails and onRenderThumbnail. However, for mobile cients, there is no dedicated way to retrieve bitmaps for annotations displayed in an annotations sidebar.
Currently, when initializing the reader with a PDF, the app immediately receives multiple onSaveAnnotations callbacks containing generated bitmap images for annotations. Mobile can use this approach for time being, but I think it's a bit unintuitive and would be better if we also had dedicated callbacks like onRenderAnnotationThumbnail for example.
