Just a very basic GLSL editor without any features. Simple, bare, minimal - just like the language.

• Updates the shader code on every edit with a debounce time of 1 second.
• Supports high DPI displays.
• Shader errors are displayed in the editor and the line is highlighted.
• Supports tab indentation (for single line only and not with selections).
• Strores the shader code in local storage.
• Revert to the default shader code with the reset button in the top right corner (most right).
• Change the resolution with the button in the top right corner. 1 = 1x, 2 = 1/2x.
• Toggle the code editor with the button in the top right corner.
• Default shader code is in the HTML.
