// If the bump-map input texture is not a standard Xbox bump-map texture format, apply a bias
// Fixes an issue where JSRF that uses unsigned texture as an input to texbem
// If the bump-map texture format is X_D3DFMT_X8L8V8U8 or X_D3DFMT_L6V5U5 we need to apply a bias
// This happens because these formats are an alias of unsigned texture formats.
// Fixes an issue with the JSRF boost-dash effect
// NOTE: This assumes that this shader will only ever be used for the input bumpmap texture
// If this causes regressions in other titles, we'll need to be smarter about this
// and include the texture formats in the shader hash, somehow.
