Texture write misalignment

[adepke]

When writing to a texture, the source placed footprint resource (upload buffer) needs to be aligned to D3D12_TEXTURE_DATA_PLACEMENT_ALIGNMENT. This is normally the case, since power of two textures are commonly added, however if a buffer with static frequency is written to that isn't aligned to 512 bytes, it will cause the next texture write to be misaligned and throw an error.
