Project16: rm2k resolution for mz

Work in progress.

Just like the title suggests, the project tries to recreate rm2k or rm2k3 like UI that renders in clear pixel art style. It still uses 48x48 tilesets, but it tries to make sure everything is aligned with 3x3 grids, so it can be displayed clearly in a window 1/3 of its original size.

The project uses Opentype Pixel Font Renderer to draw text. The demo uses ark pixel font as its main font, and 5x5 pixel font for status gauge and some small texts.
