Fix PNG resolution metadata.

Fixes Bug #2969451: MathTextParser parse fails on nested brackets. Add test for this case.

Improvements to DateLocators to partially address #2976576:
- Take into account "interval" when determining autorange (particularly important for expanding singular ranges)
- prevent a near-infinite loop in the "dateutil.rrule.between" method (calculating a repeating event between two dates) by estimating with division the approximate number, and if this number is way more than reasonable, raise an Exception.

Axes.annotate sets _remove_method

Improve backend_qt4 so it displays figures with the correct size

hist: accept a list of scalars as equivalent to a 1-D ndarray

Change "import numpy as npy" to common convention "import numpy as np"

Leave in some extra debugging information related to fonts.

Use case-insensitive matching for font names in family set lists (rcParams font.serif, font.sans-serif etc.)

Line2D: don't use subslices with markevery
