Plot Raster Images Interactively on a Plain HTML Canvas

Provides methods for plotting potentially large (raster) images interactively on a plain HTML canvas. In contrast to package 'mapview' data are plotted without background map, but data can be projected to any spatial coordinate reference system. Supports plotting of classes 'RasterLayer', 'RasterStack', 'RasterBrick' (from package 'raster') as well as 'png' files located on disk. Interactivity includes zooming, panning, and mouse location information. In case of multi-layer 'RasterStacks' or 'RasterBricks', RGB image plots are created (similar to 'raster::plotRGB' - but interactive).

Designed for use in 'R Markdown', 'Quarto', and 'Shiny' applications. The singleQuestion() quiz design was inspired by Ozzie Kirkby < https://codepen.io/ozzie/pen/pvrVLm>.
