Perform scanline-based OBB rotation on GPU.

Extracts a rotated OBB from an axis-aligned AABB using GPU acceleration. All buffers must be in GPU memory.

Parameters

aabb_pixels	Input AABB pixels (RGBA, GPU memory)
obb_pixels	Output OBB pixels (RGBA, GPU memory, must be pre-allocated)
aabb_width	Width of input AABB
aabb_height	Height of input AABB
aabb_pitch	Pitch (stride) of AABB in bytes
obb_width	Width of output OBB
obb_height	Height of output OBB
obb_cx	Center X of OBB in AABB space
obb_cy	Center Y of OBB in AABB space
angle_rad	Rotation angle in radians
stream	CUDA stream for async execution (use 0 for default stream)
