Options

Enabled 2D array textures

- Implemented mipmap generation and completeness checks for Texture2DArray. - Fixed texture parameters setters and getters along with mipmap generation functions to use the proper 2D array texture instead of the 3D texture for 2D array textures. - Enabled the same path as 3D texture for 2D array textures in the sampler. - Added an address function for the w component, which simply clamps the rounded value for 2D array textures and adapted SamplerCore::computeIndices to this new behavior.
