[WIP/QRCoder2] System.Drawing vs X

[codebude]

Topic - Part A

Should we keep System.Drawing.Common based renderers and add new ones with library 'X' or do we ditch System.Drawing.Common completely and replace it with library 'X'?

Topic - Part B

In past discussions, several libraries have been mentioned as replacements for System.Drawing. Among others ImageSharp (now partly has to be licensed?), SkiaSharp (native dependencies under Linux), Maui.Graphics or something else?

Part A

I suggest maintaining the existing code. While it's usefulness is likely declining, I see no reason to pitch the existing code. It will certainly be useful for existing users that wish to upgrade to 2.x, and serves as a template (if we like the design pattern) for SkiaSharp / ImageSharp / etc.

Part B

I suggest 'whatever contributors wish to offer PRs for'. Ideally:

• System.Drawing.Common
• SkiaSharp
• ImageSharp 2.x
• ImageSharp (latest)
• Maui.Graphics

Compare to ZXing.Net which has these NuGet packages available:

• ZXing.Net.Bindings.Windows.Compatibility
• ZXing.Net.Bindings.SkiaSharp
• ZXing.Net.Bindings.ImageSharp
• ZXing.Net.Bindings.ImageSharp.V2

ImageSharp is your friend.
