/**
* Load an array of icon textures.
* <p>
* We assume that the textures being loaded are icons, and therefore are
* roughly the same size (with a maximum of (width,height).
* <p>
* The array is limited to GL_MAX_ARRAY_TEXTURE_LAYERS layers. This can be
* fairly low (512 on low-end systems), so icons are loaded into an 8x8 icon
* matrix in each layer, thus giving a maximum of 512x8x8=32768 icons. (This
* assumes that GL_MAX_3D_TEXTURE_SIZE is big enough to take that many
* pixels. With the current icon size of 256x256, then
* GL_MAX_3D_TEXTURE_SIZE must be at least 2048.)
* <p>
* Icons that are smaller than (width,height) are offset so they are
* centred, so the shader can just draw the icons without worrying about
* where in the texture they are.
* <p>
* It appears that the images must have a row length that is a multiple of
* four. This is probably due to the particular format we're using, and
* could probably be worked around, but the simple fix is to check your row
* length.
