Import BMP to Astropaint canvas. Will need to decide:

• Which BMP formats to support (e.g., 4-bit, 16-bit, RLE compressed, row-flipped)
• Whether to try to use imported BMP's color data
• Whether to reject or try to convert BMPs that are too large or have too many colors
• Whether to try to automatically set color boundary

Moving the color boundary is slow (around 2 seconds) because each movement requires changing the style of 400-800 divs, and 202 of these are redrawing the boundary itself (a CSS border added to 102 divs and removed from 102 divs).

There are a lot of ways to improve the sluggishness; one easy fix could be making the boundary its own div that floats on top of or underneath the Astropaint screen.

Some day, it might make sense to move to HTML5 canvas, but having each pixel be a div has benefits as well (namely, easily recoloring by div class), and it'll be a lot of work to refactor just to improve the speed on this one feature. Open to suggestions and PRs!

Likely related to different implementation of mousedown/mouseover/mouseenter.

I've ruled out mobile phone support because Astrocade dev is essentially impossible to do from a mobile device. However, it would be nice to add touch support to draw on Astropaint screen from touchscreen desktops.

Add a button to let users save a screenshot from Astropaint canvas. Need to decide how much to scale up pixels.

Build compiled ROM by inserting pixel data, boundary position, and selected palettes into a standard Astrocade ROM with bitmap display.
