find the x/y location of a character, and remember info about the previous row in case we get a move-up event (for page up, we'll have to rescan)

@brief Increment the voxel index to next intersected voxel or node and returns true if the step in time does not exceed maxTime.

@brief Swap each leaf node's buffer with the nth corresponding auxiliary buffer, where n = @a bufferIdx. @return @c true if the swap was successful @p

Get the component, e.g. float f = q.w();

@brief Return the stride of the array in the x direction ( = dimY*dimZ). @note This method is required by both CopyToDense and CopyFromDense.

@brief Return the stride of the array in the y direction ( = dimZ). @note This method is required by both CopyToDense and CopyFromDense.

@brief Return the stride of the array in the z direction ( = 1). @note This method is required by both CopyToDense and CopyFromDense.

@{ Return @a x rounded up to the nearest integer.

FIXME-OPT: Need a way to reuse the result of lower_bound when doing GetInt()/SetInt() - not too bad because it only happens on explicit interaction (m
