Detailed Description

shit ahead.

So, (dt_mipmap_buffer_t *buf)->cache_entry holds a back-reference to the cache entry dt_cache_entry_t *entry. (dt_cache_entry_t *entry)->data is a reference to the dt_mipmap_buffer_dsc *dsc, which is mostly a duplicate of dt_mipmap_buffer_t *buf, adding state flags and then 64-bytes memory padding.

entry->data is an opaque, manually-handled, memory buffer holding (in this order):

• the dt_mipmap_buffer_dsc dsc structure,
• memory padding for 64-bytes alignment,
• the actual pixel buffer buf->buf (aligned to 64 bytes);

So the only way of accessing the buf->buf memory is by shifting the entry->data pointer by the size of one dt_mipmap_buffer_dsc structure.

But we need to resync the dt_mipmap_buffer_dsc dsc values with those in dt_mipmap_buffer_t *buf all the fucking time (namely, width, height, scale, color space). And then, we need to resync the buffer sizes between entry->data_size and dsc->size. But beware, because buf->size is actually the integer enum member of mipmap fixed sizes.

All in all, this clever design guarantees a maximum number of opportunities for mistakes, along with non-uniforms accesses, sometimes to dsc, sometimes to buf.

From the rest of the app, we access only dt_mipmap_buffer_t *buf, so this is our way of communicating stuff out there.
