first draft to final orientation fix:

will include:
  *full nii support
  *volume displayed in RAS space
  *volume resliced trhough TRUE axial, coronal and sagittal planes (arbitrary reslicing later on)
  *true XYToIJK/RAS in 2D views
  *reslice on deman ofr better perf
wip
wip: arbitrray reslicing
wip
use quaternions to rotate plane to XY
add 2d bounding box

todo: get spacing to be able to iterate.

then: create slices :)
bit slow and textures are incorrect in some orientation

need to take spacing into account
almost there

todo: cleaning
perf enhancing

hook to XTK rest, integrate reslice on demand
reslice ok in all directions, given any scan direction

todo: cleanup
todo:reslice on demand
todo: improve perf (<10ms)
wip
we can now choose the image resolution in x/y axis

1-
todo: clean up code
todo: get spacing in xy plane
todo: write demo
2-
todo: reslice on demand
todo: 2d renderers
todo: volume rendering
slice can now be oriented in all direction

origin issue fixed

todo: fix spacing issue
todo: slice on demand
todo: clean
todo: VR
todo: labelmaps support
fix some offset issue
wip: code cleaning
wip: cleaning reslice method
wip: generating slices with reslice2

todo: reslice on demand
todo: more cleaning
todo: fix bugs
todo: volume rendering support
todo: support create all slices through abitratry orientation
get intersection line/bounding box

to do: fix spacin issues
to do: pure sagittal and coronal shouldnt be move to xy plane
fix volume rendering
wip: renderer 2d

needs more logic to handle layers (labels maps, 2 volumes and meshes intersection)
