Yes, "texture" can potentially be a cube or rect texture. depth_blt_texture
should always be a GL_TEXURE_2D, although that might actually be a problem in
some cases if the card doesn't support NPOT textures (ie, might cause a
software fallback). This->glDescription.textureName depends on the type of the
surfaces used for the depth stencil, and can be either GL_TEXTURE_2D,
GL_TEXTURE_RECT, or a cube face.

The other issue that's less obvious, is that the depth blit shader needs to be
modified as well. It currently always uses texture2D to sample (in case of
GLSL), but that's incorrect if the texture is a cube or rect texture, of
course.
