Execution tests for the 'textureLoad' builtin function
Reads a single texel from a texture without sampling or filtering.
Returns the unfiltered texel data.
An out of bounds access occurs if:
* any element of coords is outside the range [0, textureDimensions(t, level)) for the corresponding element, or
* array_index is outside the range [0, textureNumLayers(t)), or
* level is outside the range [0, textureNumLevels(t))
If an out of bounds access occurs, the built-in function returns one of:
* The data for some texel within bounds of the texture
* A vector (0,0,0,0) or (0,0,0,1) of the appropriate type for non-depth textures
* 0.0 for depth textures
