This plugin provides a shortcode for adding a dynamic gallery of Shadertoy shaders to a website. It is designed for site owners and developers who want to showcase interactive, real-time graphics directly in their content without manual embedding. The gallery updates automatically based on a search query.

• Shortcode Integration: Use a simple [shadertoy-list] shortcode to insert a gallery into any post or page, specifying your Shadertoy API key and search terms.
• Query-Based Gallery: The gallery content is populated automatically based on a query attribute, pulling in relevant shaders from the Shadertoy platform.
• Caching for Performance: To ensure fast page loads and avoid excessive API calls, query results are cached for at least one day, and individual shader titles are cached for at least two weeks.
• Gallery Customization: Control the display with optional attributes like columns (1-4) to set the layout and sort to order shaders by criteria such as newest, popular, or name.
• User Filtering: Optionally filter the displayed shaders to only those created by a specific Shadertoy user via the username attribute.
