render3d: R3D_VKMEM=<frame> says where the GPU memory is, by owner, and the renderer's big CPU arrays

Browse source 
Every allocation carries the owner its maker was wrapped in (models, terrain, impostor atlases,
scatter, grass, shadow maps, frame targets, sky, water, game textures, made in a frame), and the
report prints each owner's images and buffers, the 25 largest images and the scatter layers',
streams' and terrain's CPU copies. Nothing drawn changes.
