62   * Max size: no limit, 0.9.18+.  4096 x 2048 or less in 0.9.17 and earlier.  (note: while there is no in-game limit apart from a mild sanity check restricting width or height to < 1073741824 and total size to < 24GiB of RAM, there is a limit if hedgewars is built w/ SDL 1.2 that restricts the maximum width to 16,384 and maximum height to 65,536)

    62   * Max size: no limit, 0.9.18+.  4096 x 2048 or less in 0.9.17 and earlier.  There are a few practical limits to map size that should be examined for people trying to make very large maps.

    63   ** SDL 1.2 - SDL 1.2 can only load maps that are 16,384px wide or less, and 65,536px high or less.

    64   ** GIMP.  GIMP 2.8 can only create PNGs that are 262,144px wide or high - is an arbitrary hardcoded sanity check.  GIMP 2.10 allows 524,288 wide or high.

    65   ** libpng - libpng can only load maps that are < 1 million px high.

    66   ** Graphics card. This is the big one. Your graphics card probably has anywhere from 256MiB to 2GiB of vRAM.  If blurry land is enabled and the map has a typical amount of empty space, you can make a map w/ ~2x the pixels as a card has vRAM. But. Most people don't like using Blurry Land, so best to limit to ~½ the pixels as a card has vRAM. Targetting support for people on 256MiB of vRAM, that means a 2:1 rectangular map should not be larger than 16,384x8192 which coincidentally fits in the SDL 1.2 width limit.

    67   ** There is also a completely arbitrary check in game for widths/height < ~billion pixels which avoids possible integer issues, and a limit on size in pixels of 6 billion or so, which was just a basic sanity limit.  However given the limitations above, these are not likely to be reached.
