NaN or divisions by 0.0 as floating-point exceptions (FPE). This is a problem with some libraries which expect that e.g. "NaN * 3.0" is NaN or "4.0 / 0" is INFINITY.
- The (strange) default behavior can be changed by setting the control word of the FPU. This is done by assigning $133F to this register via Set8087CW() in delphi. In FPC it was not available for a long time but now it is. OpenGL12.pas contained an own version of Set8087CW() which was totally wrong because the important asm-directives (fclex and fldcw) were missing so it was not of any use. Hence it was removed from the unit so it does not hide the correct FPC version anymore.
- This should fix some EDivByZero exceptions in floating-point expressions (as with projectM).

minor fixes by me.
Thank you profoX`.
This might be used as a more accurate (and faster?) alternative to the SDL conversion stuff. In addition SDL does not convert 44.1kHz to 48kHz (or vice versa) at the moment, libsamplerate does. But libsamplerate does not support mono-to-stereo or multi-channel-to-stereo conversion and it just accepts float-values so we have to convert our 16-bit int-values first.
Maybe we should use the callback-style conversion of libsamplerate.

deprecated, we should keep it here in case its removed.

This fixes the av_free_packet() errors.
Because of this bug, memory was never freed by av_free_packet and other memory areas were corrupted.
