Subject: [PATCH] ImageViewer get the Custom Texture Description from the proxy

Use the cached Texture Description for all other Textures which matches the behaviour of GetTextureData()

When saving a texture when a custom visualisation shader is in use:
- fixes a crash when saving as HDR or EXT
- fixes incorrect image saved to DDS
