VkShaderModule's may or may not be pointers depending on the target platform, so use pointers to hash those handles to be safe, and retrieve them from hashes accordingly. Fixes build on 32-bit Windows at least.

|

* 1. go to
|
||
* https://github.com/KhronosGroup/Vulkan-Headers/blob/main/include/vulkan/vulkan_core.h
|
||
* 2. Find the line where this enum value was added.

|
||
* 4. The commit you're looking at now should also change
|
||
* VK_HEADER_VERSION, find that number.
|
||
* 5. Use that number in the #ifdef when adding the enum value to
|
||
* this enum.
|
||
* 6. For the error message, look at the specification (the one
|
||
* that includes all extensions) at
|
||
* https://www.khronos.org/registry/vulkan/specs/1.0-extensions/html/vkspec.html#VkResult
|
||
* 7. If this value has not been added to the specification yet,
|
||
* search for the error message in the text of specification.
|
||
* Often it will have a description that can be used as an error
|
||
* message.
|
||
* 8. If that didn't lead to one (or you are lazy), just use the
|
||
* literal string of the enum value as the error message. A
|
||
* GTK developer will add the correct one once it's added to the
|
||
* specification.
