Path effects applied to annotation text containing \n #4024
Description
I am using the following test program with mathplotlib 1.4.0 (via anaconda) on OS X 10.10.1:
import matplotlib.pyplot as plt
import matplotlib.patheffects as pe
plt.subplot(1,1,1)
plt.annotate('line1\nline2',xy=(0.5,0.5),xycoords='axes fraction',fontsize='x-large',
path_effects=[pe.withStroke(linewidth=1,foreground='r')])
plt.show()
This fails with:
AttributeError: GraphicsContextBase instance has no attribute 'draw_path'
Removing the \n from the text or removing the path_effects option both run as expected. Any workarounds you can suggest are appreciated.

Definitely a problem with the MacOS backend and probably affects other backends which use a stack-based graphics context

@dkirkby This should be resolved with PR #4201 and #4202.
The workaround without these fixes applied is to separate out the annotation into separate annotations (without the newline).

I don't think this is fixed for OSX so I will reopen #4542 fixed it for Cairo which caused this to auto close

not blocking 1.5 on this unless @mdehoon wants to.
