Perform a component-wise multiplication of two matrices
### Declaration
```glsl
mat2 matrixCompMult(mat2 x, mat2 y)
mat3 matrixCompMult(mat3 x, mat3 y)
mat4 matrixCompMult(mat4 x, mat4 y)
```
### Parameters
```x``` specifies the first matrix multiplicand.
```y``` specifies the second matrix multiplicand.
### Description
```matrixCompMult()``` performs a component-wise multiplication of two matrices, yielding a result matrix where each component, ```result[i][j]``` is computed as the scalar product of ```x[i][j]``` and ```y[i][j]```.
