R2_XORPEN = 7

src XOR dst

Pixel is an exclusive combination; commonly used for drawing temporary,
non-flickering elements like cursors, as drawing the same thing twice
restores the original background.

Key Characteristics of R2_XORPEN
Inversion/Toggling: The XOR operation is particularly useful because
drawing the same line twice in the same place restores the original
screen content. This allows for drawing temporary or "rubber-banding"
lines (common in older interactive graphics) without permanently
altering the background.

Color Behavior: The resulting color depends entirely on both the
source and destination colors. If a pixel's color component is present
in the source but not the destination (or vice-versa), it will be
present in the result. If it is present in both or neither,
it will be absent in the result.

Device Contexts: The ROP code is a property of the device context (HDC)
and only affects drawing operations made with the current pen or brush.
