Description

VK_EXT_surface_maintenance1 adds a collection of window system integration features that were intentionally left out or overlooked in the original VK_KHR_surface extension.

The new features are as follows:

• Allow querying number of min/max images from a surface for a particular presentation mode.
• Allow querying a surface’s scaled presentation capabilities.
• Allow querying a surface for the set of presentation modes which can be easily switched between without requiring swapchain recreation.
