Save texture to file

[ghost]

Ideally, there'd also be an "Save texture to file" button as part of the sidebar / image preview, to make it easier to view these textures in external tools.
Right click to "Save image as" does work to some degree (does spector.js try to undo alpha-premultiply or something? I seem to get weird pixel colors), but is very cumbersome.

From #210

We need a technical support for printing DepthStencilTexture which dataType is DEPTH24_STENCIL8.
Now this tool can only print RGBA UNSIGNED_BYTE texture(color Texture) as uniform sampler2D source.
Can this tool support printing depthStencilTexture which dataType is DEPTH24_STENCIL8 ?

Also, please store FLOAT texture as TIFF or PFM with exact float values. In its current state you convert float pixels like this:
Math.min(Math.max(<<<FLOAT-PIXEL>>>, 0), 1) * 255
..which would not work for textures which store bone matrices for skeleton animation
