To test the vtkImageMapToWindowLevelColors class the sources was uploaded on<br>

By first item: can I set texture type GL_UNSIGNED_INT_2_10_10_10_<wbr>REV?<br>

Many greyscale monitors with DVI inputs use the equation L = 0.30*R + 0.59*G<br>
+ 0.11B to convert the 24-bit RGB DVI signal into a greyscale signal. For<br>
such monitors, it is possible to create a vtkLookupTable with 4096 entries<br>
that provides distinct greyscale values via appropriately-chosen RGB values. <br>
<br>
This method works through GDI.<br>
