Better folder path for images, sounds, etc

[KOLANICH]

image and media folders make a bit odd sense. There are lot of kind of data which are not images and sounds but which can be stored or showed as images and sounds: matrices, time series (e.g. oscillogram), spectra. So I propose to move images formats to the folder grid/2d and sounds to grid/1d, also create folders grid/multi (formats which can pack multidimensional gridded data like tensors), grid/mixed (formats which can pack several formats of different dimension, like cern root) and grid/3d (voxel graphics, spatial 2d distributions of 1d data). Vector images and 3d models formats should be put into a separate folder using the same convention depending on the dimensions of the points.

The main purpose of any classification is to help people find whatever they're looking for faster. It took me more than several seconds to guess what grid/2d, grid/1d, grid/3d, grid/mixed, etc, is supposed to be → that's a fair indication of the fact that's it's a bad idea. I'm more than sure that nobody would ever search for something very common like a .png or .gif format in grid/2d.

Besides, all that "dimensions" stuff make little sense. Should regular 2D video be considered 3D (width height time)? Should a collection of mipmaps in a 2D texture be considered 3D (width height mipmap level)? How about DX10 DDS texture array — would it be 4D (width height mipmap level * texture frame)?
