# constructor:
#     Extension(name, alias="", required=False, properties=False, features=False, conditions=None, guard=False)
# The attributes:
#  - required: the generated code debug_prints "ZINK: {name} required!" and
#              returns NULL if the extension is unavailable.
#
#  - properties: enable the detection of extension properties in a physical
#                device in the generated code using vkGetPhysicalDeviceProperties2(),
#                and store the returned properties struct inside
#                `zink_device_info.{alias}_props`.
#                Example: the properties for `VK_EXT_transform_feedback`, is stored in
#                `VkPhysicalDeviceTransformFeedbackPropertiesEXT tf_props`.
#
#  - features: enable the getting extension features in a
#              device. Similar to `properties`, this stores the features
#              struct inside `zink_device_info.{alias}_feats`.
#
#  - conditions: criteria for enabling an extension. This is an array of strings,
#                where each string is a condition, and all conditions have to be true
#                for `zink_device_info.have_{name}` to be true.
#
#                The code generator will replace "$feats" and "$props" with the
#                respective variables, e.g. "$feats.nullDescriptor" becomes
#                "info->rb2_feats.nullDescriptor" in the final code for VK_EXT_robustness2.
#
#                When empty or None, the extension is enabled when the extensions
#                given by vkEnumerateDeviceExtensionProperties() include the extension.
#
#  - guard: adds a #if defined(`extension_name`)/#endif guard around the code generated for this Extension.
