In particular it seems that decomposition is slow, so the code to handle the transformation of the normal column now tries harder to avoid it, especially in the case of a scale of 1.
Also see #222
This prevents exposed joints from not being affected by a transform directly on the Character node. See panda3d/panda3d#221 for more details.
Fixes#221
This fixes error messages being generated of the form:
AL lib: (WW) alSetError: Error generated on context 0x801cf8800, code 0xa003
This is caused by alSourceUnqueueBuffers being called without first checking whether processed buffers are available using alGetSourcei.
Fixes#180
Allows accessing `base` object and several other builtins from the ShowBaseGlobal module.
It doesn't bother with builtins that are available as members of the base object such as `render` and `loader`.
Fixes#182
This is required to make the test suite run with pipelining enabled.
It's necessary to let the draw thread do these tasks because that's where the OpenGL context is bound to. However, we need to let it access the data from the calling thread, so we have to temporarily change the pipeline stage of the draw thread.
I'm not really happy about this solution; it would be better to temporarily make the context current to the app thread, but we need a window for that, which we don't currently require to be passed into that method.
This deadlock happens when another thread holds a cycler lock and then attempts to call Pipeline::remove_cycler() while Pipeline::cycle() is running on the main thread.
The fix for this problem is threefold:
* Allow remove_cycler (and add_cycler) to be called while a cycle is in progress, by introducing a second lock
* Let cycle() not block if a dirty cycler can't be locked, instead trying other cyclers first
* Adding a way to let remove_cycler() check whether a cycler is currently in use by the main thread, and yielding if so

This changes behaviour for sRGB textures, which weren't previously converting to the correct color space.
Also add unit tests for storing to PNMImage.
Closes: #212
