allow negative data log plots with OpenGL+FLTK graphics (bug #34232)
* mx-inlines.cc (mx_inline_any_positive): New function.
* lo-mappers.h (xpositive_sign (double), xpositive_sign (float)):
New functions.
* fNDArray.h, fNDArray.cc (FloatNDArray::any_element_is_positive):
New function.
* fMatrix.h, fMatrix.cc (FloatMatrix::any_element_is_positive):
New function.
* dNDArray.h, dNDArray.cc (NDArray::any_element_is_positive):
New function.
* dMatrix.h, dMatrix.cc (Matrix::any_element_is_positive):
New function.
* graphics.h.in (log_scaler::do_neg_scale): New function.
(log_scaler::scale (const Matrix&) const,
log_scaler::scale (const NDArray&) const): Call do_neg_scale if no
array elements are positive.
* graphics.cc (axes::properties::get_axis_limits): Omit zero from
positive values for log plots. Correctly widen range for all negative
log plots.
