GPU: automatically draw images with GLSL shader depending on resolution

This adds a new "Automatic" image display method which uses GLSL shaders for
most images. It only does CPU side color management for higher res images
where sending big float buffers to the GPU is likely to be a bottleneck or
cause memory usage problem.

Automatic is the default now, previously it was 2D Texture.
