Set an int parameter array by name.

#### Parameters

main

| | |
|---|---|
| name | name of the parameter array as defined by this Material |
| type | the number of components for each individual parameter |
| v | array of values to set to the named parameter array |
| offset | the number of elements in `v` to skip |
| count | the number of elements in the parameter array to set 
For example, to set a parameter array of 4 int4s:
