 * Test Description
 * ------------------------
 *  - Validates handling of invalid 2D pitch resource:
 *    -# When device pointer is `nullptr`
 *      - Expected output: do not return `hipSuccess`
 *    -# When device pointer is not aligned appropriately
 *      - Expected output: do not return `hipSuccess`
 *    -# When pitch is not aligned appropriately
 *      - Expected output: do not return `hipSuccess`
 *    -# When height is 0
 *      - Expected output: do not return `hipSuccess`
 *    -# When height is 0 and device pointer is `nullptr`
 *      - Expected output: do not return `hipSuccess`
 *    -# When height is `size_t` maximum
 *      - Expected output: do not return `hipSuccess`
 *    -# When width is 0
 *      - Expected output: do not return `hipSuccess`
 *    -# When width is 0 and device pointer is `nullptr`
 *      - Expected output: do not return `hipSuccess`
 *    -# When width is `size_t` maximum
 *      - Expected output: do not return `hipSuccess`
 *    -# When pitch is `size_t` maximum
 *      - Expected output: do not return `hipSuccess`
 * Test source

 * Test requirements
 * ------------------------
 *  - Textures supported on device
 *  - HIP_VERSION >= 5.2
