[Paraview] Raw File Reader

After fiddling around a little bit with the raw files, I managed to
load it properly into ParaView (heeren_example_rgb_planar.raw).
Here are the settings for the reader:
File Prefix: /home/berk/heeren_example_rgb_planar.raw
File Pattern: %s
Data Type: Unsigned char
Byte Order: Little Endian
Origin: 0 0 0
Spacing: 1 1 1 (you might have to play with spacing, I didn't know the
values)
Extent: 0 511 0 511 0 0
Num. Components: 1

To load a stack of images, you will have to change the file prefix,
file pattern and the last value of the extent.
