@warning All flags except `USAGE_DEFAULT` are experimental.
@warning For the OpenCL allocator, `USAGE_ALLOCATE_SHARED_MEMORY` depends on
OpenCV's optional, experimental integration with OpenCL SVM. To enable this
integration, build OpenCV using the `WITH_OPENCL_SVM=ON` CMake option and, at
runtime, call `cv::ocl::Context::getDefault().setUseSVM(true);` or similar
code. Note that SVM is incompatible with OpenCL 1.x.
