c06f35422d
This patch adds 2 small validation to DirectX backend. First, it checks if registers in descriptor tables are not overflowing, meaning they don't try to bind registers over the maximum allowed value, this is checked both on the offset and on the number of descriptors inside the range; second, it checks if samplers are being mixed with other resource types.
