struct Anchor

Convert a top-left-origin image rectangle into local Y-up geometry.

The pointer overloads and MakeQuad write six vertices for two independent triangles; MakeQuadStrip produces a separate four-vertex atlas frame. CPU-only: pixel dimensions and offsets, normalized UVs, finite [0,1] pivot and nonzero texture dimensions required. Source rectangle bounds/size are not checked. Pointer destinations must hold six Vertex2D or thirty floats (x,y,z,u,v); they are borrowed through the call. Invalid pivot/texture throws before writes.
