Changes

v0.0.1-alpha - June 17 2018

• Add a debug overlay that shows FPS, coordinates, and useful info.
• Add FPS throttling to target 60 frames per second.
• Add F12 for Screenshot key which saves the in-memory representation of the pixels you've drawn to disk as a PNG image.
• Smoothly connect dots between periods where the mouse button was held down but was moving too fast.

v0.0.0-alpha

• Basic SDL canvas that draws pixels when you click and/or drag.
• The lines drawn aren't smooth, because the mouse cursor moves too fast.

Screenshot Feature

Pressing F12 takes a screenshot and saves it on disk as a PNG.

It does NOT read the SDL canvas data for this, though. It uses an internal representation of the pixels you've been drawing, and writes that to the PNG. This is important because that same pixel data will be used for the custom level format.
