    L8 render targets through GL_R8 internal format work fine on both
Intel and Nvidia. I am attaching a small patch which can be applied on
top of Matteo's patchset (it reorders L8_UNORM format records and adds a
color fixup).
    This makes L8 render target test run and succeed, as well as a
Unity3D app, on Intel card also (unlike rendering to GL_LUMINANCE8).

    Just for the record, the app actually succeeds with Intel card on
Windows 7 in a different way. It creates d3d11 device there (which fails
under Wine for Intel card and succeeds under Windows 7), then (on
Windows) falls back to Directx 9 rendering, but taking completely
different path on caps estimation (takes it from its builtin per-vendor
tables). When it fails with d3d11 device creation under Wine, it checks
formats through CheckDeviceFormat and ultimately refuses to create some
of the textures if D3DFMT_L8 is not supported as render target (while
works seemingly flawless when it is).
