| void CalcHistogram | ( | ) |
Calculate the histogram contents based on the global voldat[] volume array.
our class container
the maximum content of all classes
only do this if we actually have something to compute it for
this is done with the float data instead of the raw data because that way the bias/gain/gamma functions are reflected in the histogram
logarithmize the whole thing, otherwise you won't see a lot (the 0 class would be dominant)
now generate a texture out of that information and bind it to our context

| void CreateInterpolatedHandle | ( | histo_handle & | newone, | |

Take a reference to a handle, and a position, and then fill the handle with interpolated values based on the position.
first, find the handles to the left and right of the requested position
then, calculate a weighting for the handle we place in between
finally, blend
| new_pos | reference to the handle that should hold the interpolated values position for which the interpolation should occur |

| void DrawHistogram | ( | HWND | hWnd | ) |
Draw the histogram by first filling the background with a quad mapped with the texture from CalcHistogram(), and then drawing the transfer function on top.
draw a viewport-filling quad mapped with our texture
draw the transfer function handles
draw a blended polygon with the diffuse colors (looks prettier)
draw a line connecting it to the next handle
draw a box at the current handle's location
