Mandlebrot (slow) broken since circa October 2018

[hiiamboris]

At least on W7, it shows nothing - only white window.

Line 55 https://github.com/red/code/blob/8bc261749fbf9920e2155c077411c64e7c1bdae8/Scripts/mandelbrot.red#L55 should be changed to:

		img/image: img/image

for it to work

[hiiamboris]

If it's a platform discrepancy, let's raise an issue on red/red

[9214]

That was already reported during internal regression testing, among the other bugs in red/code, for all backends.

Alright

[qtxie]

Works fine on Win10.

@hiiamboris is this still broken on Win7? If so, @qtxie is the proper fix to not use show img (and note why that doesn't work in docs somewhere), address the regression, or just say it's a Win7 limitation?

No access to W7 atm.
