Detailed Description

Regression tests for Buttonwrapsizer (the Greek/symbol sidebars' wrap sizer).

The sizer overrides CalcMin() to give every button a uniform, row-filling width, which depends on wxWrapSizer's protected m_availSize. That member is -1 until the first RepositionChildren(), and using it while invalid produced a negative button width that stopped the sidebars wrapping into lines (broke on wxWidgets 3.3). These tests lay out real buttons and check they wrap onto more than one row and never get a non-positive width.
