intrinsics.def: Tighten up texture constraints Nothing was limiting the texel format to i32, u32, f32, and so the resolver was accepting any type here, and things would break in the backends. Also limit texture access controls to read or write. read_write is not supported for textures currently.

////////////////////////////////////////////////////////////////////////////////
// Intrinsic Functions //
// //
// The intrinsic function declarations below declare all the built-in //
// functions supported by the WGSL language. This intrinsic definition //
// language supports simple static-type function declarations, as well as //
// single overload declarations that can match a number of different //
// argument types via the use of 'open-types' and 'open-numbers'. //
// //
// * Basic example: //
// //
// fn isInf(f32) -> bool //
// //
// Declares an overload of the function 'isInf' that accepts a single //
// parameter of type 'f32' and returns a 'bool'. //
// //
// An 'open-type' can be thought as a template type that is determined by the //
// arguments to the intrinsic. //
// //
// * Open-type example without constraint: //
// //
// fn arrayLength<T>(array<T>) -> u32 //
// //
// Declares an overload of the function 'arrayLength' that accepts a //
// single argument of an array type with no constraints on the array //
// element type. This overload will always return a value of the same type //
// as its single argument. //
// //
// * Open-type example with constraint: //
// //
// fn abs<T: fiu32>(T) -> T //
// //
// Declares an overload of the function 'abs' that accepts a single //
// argument of type 'f32', 'i32' or 'u32', which returns a value of the //
// same argument type. //
// //
// Similarly an 'open-number' can be thought as a template number or //
// enumerator that is determined by the arguments to the intrinsic. //
// //
// * Open-number example: //
// //
// fn dpdx<N: num>(vec<N, f32>) -> vec<N, f32> //
// //
// Declares an overload of the function 'dpdx' that accepts a single //
// argument of a variable-sized vector of 'f32', which returns a value of //
// the same argument type. //
// //
// //
// Matching algorithm: //
// ------------------- //
// //
// Prior to matching an overload, all open-types are undefined. //
// //
// Open-types become closed-types (pinned to a fixed type) on the first //
// attempt to match an argument to that open-type. //
// Once open-types are closed, they remain that type for the rest of the //
// overload evaluation. //
// //
// To better understand, let's consider the following hypothetical overload //
// declaration: //
// //
// fn foo<T: scalar>(T, T); //
// //
// T - is the open-type //
// scalar - is a matcher for the types 'f32', 'i32', 'u32' or 'bool' //
// (declared above) //
// <T: scalar> - declares the open-type T, with the constraint that T must //
// match one of 'f32', 'i32', 'u32' or 'bool'. //
// //
// The process for resolving this overload is as follows: //
// //
// (1) The overload resolver begins by attempting to match the argument //
// types from left to right. //
// The first parameter type is compared against the argument type. //
// As the open-type T has not been closed yet, T is closed as the type //
// of the first argument. //
// There's no verification that the T type is a scalar at this stage. //
// (2) The second parameter is then compared against the second argument. //
// As the open-type T is now closed, the argument type is compared //
// against the value of the closed-type of T. If the types match, then //
// the overload is still a candidate for matching, otherwise the //
// overload is no longer considered. //
// (3) If all the parameters matched, constraints on the open-types need //
// to be checked next. If the closed-type does not match the 'match' //
// constraint, then the overload is no longer considered. //
// //
// The algorithm for matching open-numbers is almost identical to open-types, //
// except of course, they match against integer numbers or enumerators //
// instead of types. //
// //
// //
// * More examples: //
// //
// fn F() //
// - Function called F. //
// No open types or numbers, no parameters, no return value //
// //
// fn F() -> RETURN_TYPE //
// - Function with RETURN_TYPE as the return type value //
// //
// fn F(f32, i32) //
// - Two fixed-type, anonymous parameters //
// //
// fn F(USAGE : f32) //
// - Single parameter with name USAGE. //
// Note: Parameter names are used by Tint to infer parameter order for //
// some intrinsic functions //
// //
// fn F<T>(T) //
// - Single parameter of unconstrained open-type T (any type) //
// //
// fn F<T: scalar>(T) //
// - Single parameter of constrained open-type T (must be a scalar) //
// //
// fn F<T: fiu32>(T) -> T //
// - Single parameter of constrained open-type T (must be a one of fiu32) //
// Return type matches parameter type //
// //
// fn F<T, N: num>(vec<N, T>) //
// - Single parameter of vector type with open-number size N and element //
// open-type T //
// //
// fn F<A: access_control>(texture_storage_1d<f32_texel_format, A>) //
// - Single parameter of texture_storage_1d type with open-number //
// access-control C, and of a texel format that is listed in //
// f32_texel_format //
// //
