A little known, undocumented feature of Blockland is the mega shot. This feature allows you to effectively use multiple screenshots to automatically create a single high resolution shot - much higher than could actually be rendered by your video card. To use it simply set $megashotScaleFactor in the console and then take DOF screenshot (ctrl + shift + P)
For example $megashotScaleFactor = 2; makes double-size screenshots, $megashotScaleFactor = 4; quadruple, etc.
Be aware that depending on your hardware it could take a long time to take these. If you take a screenshot that is larger than 2048 pixels on a side, it will not show up in the main menu preview slideshow. Mip maps are still enabled based on screen resolution so it far away textures may appear blurry in the mega shots.
The cool part about these shots is that you can later crop and re-sample them down to a lower size in your favorite image editor and end up with super crisp screenshots even if you have crappy video hardware. Example attached:
