Example:
./bin/ext_memory_object-vk_export_image_as_tex 0 0 GL_TEXTURE_2D GL_RGBA 1 64
64 1 0 1 0 1 -auto -fbo
Usage in turn gives:
Usage: ./bin/ext_memory_object-vk_export_image_as_tex <src_format> <src_tiling>
<target> <format> <num_samples> <w> <h> <z> <first_level> <num_levels>
<first_layer> <num_layers>
TODO: First two arguments do not have parser support yet and are
ignored. For now test uses hardcoded values of
VK_FORMAT_R8G8B8A8_UNORM and VK_IMAGE_TILING_LINEAR
respectively,
v2:
- pipeline setup moved into common code
- check for vkGetImageMemoryRequirements2KHR() (Fredrik)
- check that image type is supported by the device (Fredrik)
