/*
 * Software methods, why they are needed, and how they all work:
 *
 * NV04 and NV05 keep most of the state in PGRAPH context itself, but some
 * 2d engine settings are kept inside the grobjs themselves. The grobjs are
 * 3 words long on both. grobj format on NV04 is:
 *
 * word 0:
 *  - bits 0-7: class
 *  - bit 12: color key active
 *  - bit 13: clip rect active
 *  - bit 14: if set, destination surface is swizzled and taken from buffer 5
 *            [set by NV04_SWIZZLED_SURFACE], otherwise it's linear and taken
 *            from buffer 0 [set by NV04_CONTEXT_SURFACES_2D or
 *            NV03_CONTEXT_SURFACE_DST].
 *  - bits 15-17: 2d operation [aka patch config]
 *  - bit 24: patch valid [enables rendering using this object]
 *  - bit 25: surf3d valid [for tex_tri and multitex_tri only]
 * word 1:
 *  - bits 0-1: mono format
 *  - bits 8-13: color format
 *  - bits 16-31: DMA_NOTIFY instance
 * word 2:
 *  - bits 0-15: DMA_A instance
 *  - bits 16-31: DMA_B instance
 *
 * On NV05 it's:
 *
 * word 0:
 *  - bits 0-7: class
 *  - bit 12: color key active
 *  - bit 13: clip rect active
 *  - bit 14: if set, destination surface is swizzled and taken from buffer 5
 *            [set by NV04_SWIZZLED_SURFACE], otherwise it's linear and taken
 *            from buffer 0 [set by NV04_CONTEXT_SURFACES_2D or
 *            NV03_CONTEXT_SURFACE_DST].
 *  - bits 15-17: 2d operation [aka patch config]
 *  - bits 20-22: dither mode
 *  - bit 24: patch valid [enables rendering using this object]
 *  - bit 25: surface_dst/surface_color/surf2d/surf3d valid
 *  - bit 26: surface_src/surface_zeta valid
 *  - bit 27: pattern valid
 *  - bit 28: rop valid
 *  - bit 29: beta1 valid
 *  - bit 30: beta4 valid
 * word 1:
 *  - bits 0-1: mono format
 *  - bits 8-13: color format
 *  - bits 16-31: DMA_NOTIFY instance
 * word 2:
 *  - bits 0-15: DMA_A instance
 *  - bits 16-31: DMA_B instance
 *
 * NV05 will set/unset the relevant valid bits when you poke the relevant
 * object-binding methods with object of the proper type, or with the NULL
 * type. It'll only allow rendering using the grobj if all needed objects
 * are bound. The needed set of objects depends on selected operation: for
 * example rop object is needed by ROP_AND, but not by SRCCOPY_AND.
 *
 * NV04 doesn't have these methods implemented at all, and doesn't have the
 * relevant bits in grobj. Instead, it'll allow rendering whenever bit 24
 * is set. So we have to emulate them in software, internally keeping the
 * same bits as NV05 does. Since grobjs are aligned to 16 bytes on nv04,
 * but the last word isn't actually used for anything, we abuse it for this
 * purpose.
 *
 * Actually, NV05 can optionally check bit 24 too, but we disable this since
 * there's no use for it.
 *
 * For unknown reasons, NV04 implements surf3d binding in hardware as an
 * exception. Also for unknown reasons, NV04 doesn't implement the clipping
 * methods on the surf3d object, so we have to emulate them too.
