Multipaint: Draw pictures with color limitations of 8-bit and 16-bit platforms

Summary

Older notes NOTE to Raspberry Pi users (18.3.2024) My experiences have shown the program can run on Raspberry Pi 3B+ and Raspberry Pi 400. Running the 32-bit linux version may help - or not. The Processing 4 zip has a version dedicated for arm, but this isn't really necessary. Pi 400 is somewhat usable, image imports and internal conversions do take time though.The Raspbian OS makes a huge mess of the file selector, but it kind of works. There's a solution at hand but I haven't implemented it yet.Have a reasonable desktop resolution so you can use a smaller Multipaint app window. NOTE to Windows users (12.2.2023) I have disabled the specific file selector for Windows, because it apparently caused some trouble. If you want to enable the better fileselector for Windows, check the prefs.txt file in the data folder and alter the line to read FSELECTOR=1 Windows 10: If you encounter a problem where resizing the Multipaint window makes the window unresponsive (immobile, non-resizable) or otherwise crashes the program, you may need to update your Windows. On a 20H2 it seemed to work fine. Your security software may tag the Multipaint archive as a potential malware/virus just in principle, which ALMOST certainly is a false positive. Furthermore, like with Mac, your security settings may prevent you from running web-downloaded content. Take care! NOTE to Mac users (24.11.2020) Tested on Yosemite 10.10.5, Catalina 10.15.7 and El Capitan 10.11.6. There may be security/ file quarantine related issues with the Macintosh. You may need to allow the file to run separetely from your privace/security settings. Depending on your Mac OS and Java version, the application may have problems with finding the prefs.txt file. This should no longer be a problem with the 2020 version. See further below for more information. NOTE to Linux users (24.11.2020) The application window resize didn't work properly on some Linux setups. Marq (of the PETSCII editor fame) found a solution and it has been...
