Behaviour for browsers without WebGL support

[jritch]

I am attempting to view this book from a browser without WebGL support. I see the content of the book briefly load before being replaced by the error message

It does not appear your computer can support WebGL.

I do not have control over my browser (I am unable to update to a newer version that includes WebGL), but I am still interested in reading the text content of the book.

Manually going through the pages in this repository is a fine workaround for me, but I think that in general it would be less painful for readers in my situation if the text was still accessible from the main web page, and the above error message replaced the individual demos that make use of WebGL, instead of all the content.

Love the book, though!

Totally true. I will work on that on glslCanvas. You can still read the book from the github repository or making it a .pdf ( https://github.com/patriciogonzalezvivo/thebookofshaders/tree/master/appendix#how-to-print-this-book )

Moving the issue here: patriciogonzalezvivo/glslCanvas#12 for more consistency! Maybe we can close this one, what do you think @jritch?

I have the same issue, using macOS 10.13.6, chrome version 70.0.3538.102, (64 bit). Tried to connect from Russia and Italy via VPN service - the same problem, so that's not a firewall issue. Tried to use normal and Incognito modes, does not change anything. Though, everything works fine if I open this site in Safari browser.
