In drawing two rectangles and with one rectangle in hatch style, the thickness of the hatch line may be incorrectly drawn

[cywsnlam]

Operating system: macOS High Sierra (Version 10.3.5) wxPython version: wxPython-4.0.1.dist Stock or custom build: Stock Python version: Python 3.6 Stock or custom build: Stock

Description of the problem:

When creating wx.Brush() with style BRUSHSTYLE_VERTICAL_HATCH, or other hatch style alike, to draw ractangle, and together drawing with other rectangle with different border thickness, the hatch line thinkness is not correctly reflected. (Pls. run and see sample code demonstrated.)

Pls. see attached sample code demonstrated. Thanks.

This is looking like an issue with wxWidgets' underlying implementation on wxOSX
