Changes (by saraedum):

 * branch:  u/saraedum/ticket/15915 => u/malb/t15915_discrete_gaussians


Comment:

 A few questions (line numbers are all in the version I pushed):

 * Should it really be x-2 in line 518 of dgs_gauss.h?

 * What is the TODO in line dgs_gauss_dp.c?

 * `self->c_r = 0.0;` after an abort() in line 114 and 130 of
 dgs_gaus_dp.c?

 * What is "this `B`" in line 186 of discrete_gaussian_lattice.py?
