p5.Framebuffer.get() loses resolution at pixel density > 1

[MASTERsj01]

Increasing access

Fixing this ensures that p5.Framebuffer.get() returns high-resolution images on high-DPI displays (like Retina screens), matching user expectations. Currently it silently downsizes the image, which can confuse beginners who don't understand pixel density.

Feature enhancement details

p5.Framebuffer.get() in src/webgl/p5.Framebuffer.js (line 1575) has a TODO: support get() at a pixel density > 1 comment.

Currently, when density > 1, the method reads the full high-resolution pixel data but then calls resize(w, h) which performs a lossy downscale — discarding the extra resolution.

The fix is to use p5.Image.pixelDensity(density) instead of resize(), so the returned image retains its full-resolution data while reporting the correct logical width and height.

Additionally, console.warn at line 1503 should use p5._friendlyError() for consistency with FES.
