* 3D engine now uses DeviceState too, plus new state modification tracking * Remove old methods code * Remove GpuState and friends * Optimize DeviceState, force inline some functions * This change was not supposed to go in * Proper channel initialization * Optimize state read/write methods even more * Fix debug build * Do not dirty state if the write is redundant * The YControl register should dirty either the viewport or front face state too, to update the host origin * Avoid redundant vertex buffer updates * Move state and get rid of the Ryujinx.Graphics.Gpu.State namespace * Comments and nits * Fix rebase * PR feedback * Move changed = false to improve codegen * PR feedback * Carry RyuJIT a bit more
