[Example] Style Transfer + WebGL backend exceeds maximum texture size on Dell XPS

[Honry]

Test Env: Dell XPS, Ubuntu 16.04, Kabylake i7-8550U, Intel UHD Graphics 620

When test Style Transfer with WebGL backend, throws following error:

Requested texture size [4218x4218] greater than WebGL maximum on this browser /GPU [4096x4096]

Some platform limits the max texture size to 4096x4096, I got some hint from chrome://gpu:

Driver Bug Workarouds: max_texture_size_limit_4096

This is a compatibility issue, we may need to consider to reduce the texture size.
