Ryan Holtz e028e20476 - "And he did give them CRT bloom, and it scorched their eyes so; and they wept
openly, for there was nothing left to see with" [MooglyGuy]
  * Enabled vector bloom and associated .ini controls
  * Added raster bloom and associated .ini controls, each bloom "level" is the
    linear weight of successively half-sized render targets
  * Removed D3D8 mode
  * Mass renaming in D3D renderer to use namespaces, initial planning step to
    HAL-based renderer implementation on Windows (i.e., GL on Windows)
  * Converted d3d_info, d3d_poly_info, and d3d_texture_info into classes
  * Added batching of vectors for possible speed increase
  * Minor cleanup of shader state setting
