A simple openGL-based image viewer with retro shader effects

• load images
• apply real-time effects
  • normal
  • CRT effect with scanlines
  • Pixelation with dithering

• 0 - Normal view
• 1 - CRT effect
• 2 - Pixelation effect
• U - Upload new image

Requires:

• OpenGL
• GLFWL3
• GLAD

download the pre-built version from itch.io only works on linux (zenity for window dialog).

• window resizing is not properly handled yet, I plan to add aspect ratio preservation when I have time.
• I plan to add imgui controls and more shader effects
