Dear Maintainer,

When I try to load a .heic photo:

,----
| Memory allocation error: Security limit exceeded: Allocating 599270415
| exceeds the security limit of 536870912 bytes
`----

This is a "security limit" in libheif.

Upstream don't want do fix that.

https://github.com/strukturag/libheif/issues/192

Here is a simple patch to increase this limit from 512 MB to 1GB
