The OpenGL specs require that the storage image qualifier in shaders (e.g., "rgba32f") needs to be compatible with the format of a bound image (see https://registry.khronos.org/OpenGL/specs/gl/glspec46.core.pdf#page=318). We know that Blender currently does not handle this correctly in multiple places. AMD and NVIDIA seem to silently ignore a mismatch and just seem to use the format of the bound image. However, for the Intel Windows drivers, this seems to lead to visual corruptions (#141436, #141173). While a more graceful handling of a mismatch may be nice, this is in line with the OpenGL specs. This PR adds code for validating image formats for bindings. Pull Request: https://projects.blender.org/blender/blender/pulls/143791
