=== Description
28+
29+
This extension provides per-image selection of optimal tiling arrangements
30+
by extending slink:VkImageCreateInfo with
31+
slink:VkImageTilingControlCreateInfoEXT when multiple arrangements are
32+
supported by the implementation.
33+
34+
ename:VK_IMAGE_TILING_CONTROL_DEFAULT_EXT can: be set to use the tiling
35+
arrangement that is the same selection as with the
36+
slink:VkImageTilingControlCreateInfoEXT structure omitted.
37+
38+
ename:VK_IMAGE_TILING_CONTROL_MIN_SIZE_EXT can: be set to minimize memory
39+
size requirements with reduced consideration for memory access performance.
40+
41+
ename:VK_IMAGE_TILING_CONTROL_MAX_PERFORMANCE_EXT can: be set to maximize
42+
memory access performance with reduced consideration for increases in memory
43+
size requirements.
