The dt_gui_module_t type is the intersection between a dt_lib_module_t and a dt_iop_module_t structure. It acts as an abstract class from which we can connect to the common fields of both structures, for the sake of blindly connecting bauhaus widgets without inheriting modules. Indeed, modules need to inheritate the bauhaus API to instanciate its widgets. But then, if the bauhaus API also inheritates modules, the circular dependency becomes a mess. This allows to reference parent modules in bauhaus widget without inheriting their API, and without caring if the parent is a dt_iop_module_t or a dt_lib_module_t
This module converts float32 RGBA pixels to uint8 BGRA pixels, for GUIÂ pipelines only (darkroom main preview and navigation thumbnail). It self-disables for export pipelines
