Why would the following line NOT render
But this call DOES render:

youre using it incorrectly read the spec
void DrawRangeElements( enum mode, uint start,
uint end, sizei count, enum type, void *indices );
is a restricted form of DrawElements. mode, count, type, and indices match the
corresponding arguments to DrawElements, with the additional constraint that all
values in the array indices must lie between start and end inclusive.

EDIT: I fixed it :)
Here are the correct parameters for win32 opengl (didnt test on linux yet):
Breakdown of the parameters:
Type: GL_TRIANGLES,etc
Start: - Start with first index in the array of indices
End: - The last index of array
Size: How many indices you want drawn
Type: GL_UNSIGNED_INT,etc
Pointer To Indices: set to 0 if using VBOs
I had seen a few different versions of glDrawRangeElements() on the net....
Zeek: Good call :)
