render3d: HUD text, panels and images share a draw - the font stays bound and each vertex says what it reads

Browse source 
A panel and its label alternated the white and font textures, and every switch closed the overlay's
draw range: 77-91 ranges a frame in town. The font atlas is now bound beside the image texture for the
whole flush, and v carries 4 x the vertex's mode (0 image, 1 font, 2 flat colour) on top of its real
coordinate, so only a different image texture or a clip rectangle closes a range. Town: 24 ranges.
OpenGL frames byte-identical at all five viewpoints; MoltenVK with validation adds no message.
