If the function succeeds, the return value is the handle to a display device
context for the specified window.

device context is available.
function automatically sets the clipping region of the device context to
exclude any area outside the update region. The update region is set by the InvalidateRect
function and by the system after sizing, moving, creating, scrolling, or any
other operation that affects the client area. If the update region is marked
for erasing, BeginPaint
sends a WM_ERASEBKGND message to the window.

except in response to a WM_PAINT message. Each call to BeginPaint
must have a corresponding call to the EndPaint
If the caret is in the area to be painted, BeginPaint
automatically hides the caret to prevent it from being erased.

uses that brush to erase the background of the update region before
