- Fail in NtGdiCreateClientObj, when the object type is not valid.
This is based on Windows behavior, only more strict. Windows allows to set the stock bit and reuse count, which is probably not what we want.

/*
* If you want to understand this code, you need to start thinking in portals.
* - gpaulRefCount is a global pointer to an allocated array of ULONG values,
* one for each handle. Bits 0 - 22 contain a reference count for the handle.
* It gets increased for each handle lock / reference. Bit 23 contains a valid
* bit. If this bit is 0, the handle got deleted and will be pushed to the free
* list, once all references are gone. Bits 24 - 31 contain the reuse value of
* the handle, which allows to check if the entry was changed before atomically
* exchanging the reference count.
* - Objects can exist with or without a handle
* - Objects with a handle can be locked either exclusively or shared.
* Both locks increase the handle reference count in gpaulRefCount.
* Exclusive locks also increase the BASEOBJECT's cExclusiveLock field
* and the first lock (can be acquired recursively) acquires a pushlock
* that is also stored in the BASEOBJECT.
* - Objects without a handle cannot have exclusive locks. Their reference
* count is tracked in the BASEOBJECT's ulShareCount field.
* - An object that is inserted in the handle table automatically has an
* exclusive lock. For objects that are "shared objects" (BRUSH, PALETTE, ...)
* this is the only way it can ever be exclusively locked. It prevents the
* object from being locked by another thread. A shared lock will simply fail,
* while an exclusive lock will succeed after the object was unlocked.
