The eraser checks the current, previous and next point (and sets pc0, pc1 & pc2 corresponding to that for futher occlusion/brush/clipping checks). For the very first point, it sets pc0 to pc1 [which makes sense, there is no previous point, so we should assume the previous segment is "visible" as soon as the first point is], but does so *before* pc1 is even calculated. This makes following occlusion/brush/clipping checks work with zero values [which leads to no earsing in most cases]. Now *first* calculate pc1, *then* set pc0 to pc1.
