Fix textures not getting displayed when using GL_COMPARE_REF_TO_TEXTURE

Browse Source 
This commit adds the GL_TEXTURE_COMPARE_MODE parameter to the
TextureSamplerState struct, and sets its value to GL_NONE in
SetSamplerState. This fixes the issue of depth textures that use
GL_COMPARE_REF_TO_TEXTURE being displayed as solid black or white
in the texture viewer.
