Default API: support larger images with gfx.setimgdim()

Currently images are limited to 2048x2048 which, given the resolution of today's monitors, is not as big as it used to be.

It's possible to gfx.loadimg() larger images, which makes 2k with gfx.setimgdim() feel like an artificial limitation.

IMO the dimensions allowed by gfx.setimgdim() should be at least 4k, probably even 8k.

You can overcome it, by loading a png of your desired size into that image.
It's just a workaround but works great.
Have tested it up to 10k by 10k resolution.

Yeah, I mentioned above that gfx.loadimg() supports much larger images, and in fact I have been doing this exact trick myself.

It just seemed arbitrary given that the underlying support for large images was clearly there, hence this FR.

The scenario that prompted me to start this thread was loading a large image from disk and I wanted a clone of the image that included some simple post-processing (inverting colors basically). It seemed clunky that I needed to load the image twice from disk, as opposed to once and just blitting it over to a separate buffer created with gfx.setimgdim().

You can load bigger images - but still cannot draw/write into that image beyond 2048x2048 pixels - at least last time I tried this.

So it's only a good workaround if you aren't needing to alter that image (for instance - using it as a changing part of a GUI).

So +1000 again for the feature request...

I managed to draw beyond 2048 into a bigger picture. I did it on Windows but haven't tested it on Mac/Linux.
