Detailed Description

Specify swath region to wait on during asynchronous decompression.

Input: Set pixel coordinates (x0, y0, x1, y1) before calling grk_decompress_wait(). Output: After grk_decompress_wait() returns, tile_x0/y0/x1/y1 and num_tile_cols are populated with the tile grid indices covering the requested swath. These can be used with grk_decompress_get_tile_image() to retrieve per-tile decoded data.

Note: tile coordinates are only populated when grk_decompress_wait() is called with a non-null swath pointer and asynchronous+simulate_synchronous mode is enabled.
