Hi,
When I combine mathtext with the stixsans fonts while mathtext.default is set to ‘regular’, horizontal text is not vertically aligned properly, like the baseline is moving. I’ve attached an image of what I see when I run the following code. It should be noted that I don’t see anything like this on the vertical axis, and it all goes away if I stop using mathtext.
import matplotlib.pyplot as plt
from matplotlib import rcParams
rcParams[‘font.size’] = 12.0
rcParams[‘mathtext.default’] = ‘regular’
rcParams[‘mathtext.fontset’] = ‘stixsans’
fig = plt.figure()
plt.xlabel(‘ItLooksToMeLikeTheBaselineMoves $(g m^{-3})$’)
plt.ylabel(‘ItLooksToMeLikeTheBaselineMoves $(db km^{-1})$’)
plt.show()
Thoughts? Am I doing something bad? Can anyone else reproduce this?

It seems the Freetype rendering backend wasn't doing subpixel alignment on the text, but was being rounded to the nearest pixels. Taking the fractional part into account seems to resolve this. Fixed on branch and trunk.

I'm having a problem with the rendering of stixsans fonts again. Not
as bad as the baseline before, but some odd text placement:
import matplotlib.pyplot as plt
from matplotlib import rcParams
rcParams['font.size'] = 8.0
rcParams['mathtext.default'] = 'regular'
rcParams['mathtext.fontset'] = 'stixsans'
fig = plt.figure(dpi=100)
plt.text(0.5,0.5,'Velocity \\,Spectrum \\, \(m \\,s^\{\-1\}\)')
plt.show()
I've attached images from both the 'regular' setting above and for
'mathtext.default' set to 'rm', which actually makes things
worse. It's also quite noticable for larger font sizes with 'rm'.
Thoughts?
