- Update known-good
- Generate source
- Remove vk_layer_settings_ext.h
- Change all usage of VkLayerSettingEXT::count to use the new name
valueCount from the public header.
After VK_EXT_layer_settings spec review, this new type
was judge unnecessary because it could be express by
three uint32. However, it still remains useful for the
layer settings library to correctly interpret formated
strings that represent "framesets".
- We need to use a different number and name to avoid conflict with the old extension
- Improve vlInitLayerSettings API to map GetProperties approach
- Settings may have no value
