Subject: Allow GL_RGB9_E5 as a valid fbo format
X-Git-Tag: upstream/1.3.5~550^2~8^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=95fae23679bf1717083797c4ff792666d610f5d4;p=platform%2Fupstream%2FVK-GL-CTS.git

Allow GL_RGB9_E5 as a valid fbo format

If GL_QCOM_render_shared_exponent is available then treat
GL_RGB9_E5 as a valid internal format for fbo. Also, allow
copy of RGB9_E5 pixel data.

Components: OpenGL
VK-GL-CTS Issue: 2898

Affects:
KHR-GLES3.packed_pixels.rectangle.rgb9_e5
KHR-GLES3.packed_pixels.pbo_rectangle.rgb9_e5
KHR-GLES3.packed_pixels.varied_rectangle.rgb9_e5
