Subject: Fix required sample count tests
X-Git-Tag: upstream/0.1.0~662^2^2~10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8753a9e7528ca67b25bfabb4f03915a25721a690;p=platform%2Fupstream%2FVK-GL-CTS.git

Fix required sample count tests

According to,

   Table 11.1. Image and image view parameter compatibility requirements

Only non-cube images with type VK_IMAGE_TYPE_2D can have sample counts
greater than one.

In addition, the following properties should hold for multisampled
images: the formats must support being used in a color or depth/stencil
attachment, or in a storage image when shaderStorageImageMultisample is
supported. Images not fitting the above descriptions may have a sample
count of one or zero (in error conditions). Align tests for sample
counts to this behavior.

(cherry picked from commit dc4227d5ec87080f5dad810b5e33ae3b3fa014a4)
