ldk_renderer_draw_line

Submit an unlit, capped triangular prism from start to end. Thickness is the circumdiameter of its cross-section, in world units. Depth test also enables depth writes; false uses the overlay path. View may be ALL or an ID not yet submitted. Call on the render thread before render_frame; the queue is cleared after that frame is rendered. Zero-length segments succeed without drawing. Invalid/nonfinite data, nonpositive thickness and allocation failures return false.
