Subject: SparseTextureAlloc check for GL_NV_deep_texture3D
X-Git-Tag: upstream/1.3.5~852^2~71
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7e9411eff23d4589f7db0dc717d0ac53575672da;p=platform%2Fupstream%2FVK-GL-CTS.git

SparseTextureAlloc check for GL_NV_deep_texture3D

When running the
SparseTextureAllocationTestCase::verifyTexStorageInvalidValueErrors test
we need to check if the GL_NV_deep_texture3D extension is supported. If
so we can't compare the depth of the texture against the
GL_MAX_3D_TEXTURE_SIZE attribute that is intended for symmetric texture
limits. Instead we need to check against GL_MAX_DEEP_3D_TEXTURE_DEPTH_NV
provided the texture width and height are within the acceptable ranges
for a deep texture.

Components: OpenGL

VK-GL-CTS issue: 959
