Allow additional window styles #55
Description
Is your feature request related to a problem? Please describe.
For a separate project which uses maxGUI, I've needed to alter maxGUI code to allow different window styles.
For example, a window style for owning the form's device context, and another for events on horizontal and vertical resize triggering paint.
Describe the solution you'd like
First, research if any of these should be on by default anyway. Maybe they don't really need to be exposed.
Second, for ones that do need to be exposed find a good way to make that option available.
Describe alternatives you've considered
For now, I've just hard-coded the change in my separate project and not upstreamed it. This technically is an option, but I don't think it is a good option. It isn't a deliberate escape hatch. It is more of an oversight.
