+    Slight improvement in management of code block chunks
+    
+    Instead of having the chunk array at the segment level, we can move it down to
+    the codeblock itself since segments are filled in sequential order.
+    Limit the number of memory allocation, and decrease slightly the memory usage.

+
+    Decoding: do not allocate memory for the codestream of each codeblock
+    
+    Currently we allocate at least 8192 bytes for each codeblock, and copy
+    the relevant parts of the codestream in that per-codeblock buffer as we
+    decode packets.
+    As the whole codestream for the tile is ingested in memory and alive
+    during the decoding, we can directly point to it instead of copying. But
+    to do that, we need an intermediate concept, a 'chunk' of code-stream segment,
+    given that segments may be made of data at different places in the code-stream
+    when quality layers are used.
+    
+    With that change, the decoding of MAPA_005.jp2 goes down from the previous
+    improvement of 2.7 GB down to 1.9 GB.
+    
+    New profile:

+
+    Add opj_image_data_alloc() / opj_image_data_free()
+    
+    As bin/common/color.c used to directly call malloc()/free(), we need
+    to export functions dedicated to allocating/freeing image component data.

+    Fix crash on Windows due to b7594c0fcb9dd3aa6356d72c4a525d76168da689
+    
+    b7594c0fcb9dd3aa6356d72c4a525d76168da689 may put opj_tcd_tilecomp_t-&gt;data
+    allocated by opj_alloc_tile_component_data() as the image-&gt;comps[].data. As
+    opj_alloc_tile_component_data() use opj_aligned_malloc() we must be sure to
+    ue opj_alined_malloc()/_free() in all places where we alloc/free
+    image-&gt;comps[].data.
+    
+    Note: this might have some compatibility impact in case user code does itself
+    the allocation/free of image-&gt;comps[].data
