# Windows delayload DLLs.
# Delayload most libraries as the DLLs are simply not required at startup (or
# at all, depending on the process type). Some dlls open handles when they are
# loaded, and we may not want them to be loaded in renderers or other sandboxed
# processes. Conversely, some DLLs must be loaded before sandbox lockdown. In
# unsandboxed processes they will load when first needed. The linker will
# automatically ignore anything which is not linked to the binary at all (it is
# harmless to have an unmatched /delayload). This list should be kept in sync
# with Chromium's "delayloads" target from the //build/config/win/BUILD.gn file.
