Increasing access

Using p5._friendlyError() ensures framebuffer configuration warnings are displayed consistently and can be suppressed via p5.disableFriendlyErrors.

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 enhancement details

src/webgl/p5.Framebuffer.js uses 11 console.warn calls instead of p5._friendlyError():

• Line 185: Antialiasing unsupported in WebGL 1
• Lines 199-203: Missing width/height dimensions
• Line 212: Stencil without depth buffer
• Lines 487-490: Depth texture unavailable
• Lines 499-502: FLOAT depth format in WebGL 1
• Lines 511-515: Unknown framebuffer format
• Lines 522-525: Unknown depth format
• Lines 531-534: FLOAT textures unsupported
• Lines 542-545: FLOAT depth textures unsupported
• Lines 549-552: HALF_FLOAT textures unsupported
• Lines 560-563: RGB with FLOAT/HALF_FLOAT

I have a PR ready.
