This, in combination with ebef9f3de8d2eb1c3628a25fe3bd08aa59c8804d, makes it easier to catch issues in code that is accidentally letting get temporary TransformState objects get destroyed. It does not affect release builds.
In older BAM files (version <= 6.42), _fixed_depth will have an uncertain value after loading, leading to incorrect transform calculations, which cause rendering issues (see issue #474)
Shaders without #version line (which are supposed to indicate GLSL 1.10) will be interpreted differently by different drivers, so this is almost certainly a mistake. In the future, we can forbid this altogether or insert #version 110 automatically.
This implements a slightly different solution for #311 that maintains the behaviour for the fade screen to prevent clicks from propagating to the geometry below it.

Let's show a warning when an option has been removed but its presence would not have affected the build in an important way. For options like --use-awesomium we should still show an error since it invokes behavior we no longer support, but it should be harmless to specify --no-awesomium.
This is used similar to matches() but for file paths: it does not match slashes for * characters and has special support for /**/ and ignores // and /./ patterns.
This makes it possible to use BillboardEffect to specify a fixed distance to the camera, in order to keep them at a fixed apparent size.
This also enables serialization to .bam of the reference NodePaths of BillboardEffect and CompassEffect.
c18abad8c3373aff134dd02d099d476d094b0b69 added a call that resets the m_isInContact flag, so this resets it, for better or worse. We may want to revisit whether #349 was indeed the right fix to #250.
Fixes#453
Officially, in core profile OpenGL 3.2+, calling it with a value higher than 1.0 is an error, but many vendors seem to let us. Apple's implementation does not. It appears that checking the maximum line width is a way to deal with this.
Fixes#466
Functions get_point_a() and get_point_b() appear to return the top of the cylinder section of the tube, not the tip of the endcap, making subtracting the radius unnecessary.
Even a brief error message in the assertion is infinitely more useful to a user who is not at home in the source code, especially for assertions that may reasonably be triggered by honest user mistakes.
