/////////////////////////////  DRIVER CAPABILITIES  ////////////////////////////

//  The Cg compiler uses different "profiles" with different capabilities.
//  This shader requires a Cg compilation profile >= arbfp1, but a few options
//  require higher profiles like fp30 or fp40.  The shader can't detect profile
//  or driver capabilities, so instead you must comment or uncomment the lines
//  below with "//" before "#define."  Disable an option if you get compilation
//  errors resembling those listed.  Generally speaking, all of these options
//  will run on nVidia cards, but only _DRIVERS_ALLOW_TEX2DBIAS (if that) is
//  likely to run on ATI/AMD, due to the Cg compiler's profile limitations.

//  Derivatives: Unsupported on fp20, ps_1_1, ps_1_2, ps_1_3, and arbfp1.
//  Among other things, derivatives help us fix anisotropic filtering artifacts
//  with curved manually tiled phosphor mask coords.  Related errors:
//  error C3004: function "float2 ddx(float2);" not supported in this profile
//  error C3004: function "float2 ddy(float2);" not supported in this profile
#ifndef _DRIVERS_ALLOW_DERIVATIVES
    #define _DRIVERS_ALLOW_DERIVATIVES 0
#endif

//  Fine derivatives: Unsupported on older ATI cards.
//  Fine derivatives enable 2x2 fragment block communication, letting us perform
//  fast single-pass blur operations.  If your card uses coarse derivatives and
//  these are enabled, blurs could look broken.  Derivatives are a prerequisite.
#if _DRIVERS_ALLOW_DERIVATIVES

//  Dynamic looping: Requires an fp30 or newer profile.
//  This makes phosphor mask resampling faster in some cases.  Related errors:

//  be unrolled

//  is wrong (loops are allowed), breaking a loop into if-blocked pieces with a
//  binary search can potentially save some iterations.  However, it may fail:

//  error C6002: Instruction limit of 1024 exceeded: 1523 instructions needed
//  to compile program.
//  Enabling integrated graphics compatibility mode will automatically disable:
//  1.) _PHOSPHOR_MASK_MANUALLY_RESIZE: The phosphor mask will be softer.
