Support for pasting images

[voithos]

It'd be really nice if Lorien supported pasting in images (and moving / resizing them). This would be useful in augmenting the free-form brainstorming that's already possible with some specific images/screenshots.

Thanks again for the cool tool. :)

I started working on adding image-paste support via external C++ library clip since Godot can only retrieve text from clipboard. Currently, I have only tested on Linux since I do not have macOS or Windows development environments ready.

• https://github.com/hansemro/GDClip: clip library for Godot + demo
  • tested image formats confirmed working: png, jpeg, bmp, tiff, static gif

• https://github.com/hansemro/Lorien/tree/paste_poc: Linux/xclip image paste proof-of-concept in Lorien
  • no load/save/selection/deletion functionality for pasted images as they have not been implemented yet.
  • supports only png images in clipboard

@hansemro impressive! We can use this when we add full image support ;)

I would have just started with dragging images into the app window (which you can do with Godot) and then implement everything based on that. But unfortunally i'm very busy right now, so i'm of very little help for such a big new feature :/

I am nearly finished with clipboard support using GDClip (which is ready). Current status: https://github.com/hansemro/Lorien/issues/1

Let me know if you are interested in a merge request (without super-eraser + debug stuff)

Added builds for Windows/macOS/Linux: https://github.com/hansemro/Lorien/releases/tag/v0.5.0-gdclip-super-eraser-dev-r1
