Add a version of Processing's loadShader() function to p5.js

[Metamere]

Increasing access

It would provide a utility and convenience function. It would allow for a smaller main script, which could make things easier to manage, especially when working in the on-line editor with large shader files.

Most appropriate sub-area of p5.js?

• Accessibility
• Color
• Core/Environment/Rendering
• Data
• DOM
• Events
• Image
• IO
• Math
• Typography
• Utilities
• WebGL
• Build process
• Unit testing
• Internationalization
• Friendly errors
• Other (specify if possible)

Feature request details

p5.js now has a createFilterShader() function where one can create a filter from just a fragment shader, which needs to be defined in the main script file. It would make sense to provide a loadFilterShader() function to allow for creating a filter shader by loading from a separate file, just like loadShader() provides that utility to accompany the createShader function. It would keep things consistent.

This is already available here or are you thinking of something else?

@limzykenneth I think they're referring to an equivalent of createFilterShader, which does the vertex shader for you and makes sure it's bound to the right WebGL context automatically. We don't have a load* equivalent for that just yet, so it would make sense to me to add it for consistency

@limzykenneth, @davepagurek, you're both correct. I was trying to help by creating this to address an issue someone else brought up, but I misunderstood and messed it up initially. Hopefully the current version is correct.
