Fix pack and unpack include file to properly work under MSVC as well. Needs to suppress warning as we don't have the push and pop together anymore.
Fix push and pop usage - some files forgot to add the define, so effectively not work under gcc with special architectures - and move all files to use the new include files.

Fix framebuffer postfix absence when not using extension pointers. Just use the so far only for OSX used version without _ARB postfix. Fix BlendEquationIndexed code which was wrongly copy-pasted.

Merge from 1.7 branch, revisions 4090-4187. Device fixes, serialization bug fix, some compilation warnings. Bug in color conversion fixed, and some demo fixes.

Remove test isPointInsideWithSinglePrecision as triangle3d::isPointInside now rather includes more border points than risking to miss some anyway.

Fix screenshots under Linux/OpenGL for formats ECF_R5G6B5 (failed before) and ECF_R8G8B8 (red and blue where switched). Note that R5G6B5 still has strange results when writing to file. But that's due to a bug in color-conversion, which is fixed already in 1.7 and will be merged to trunk soon.

- triangle3d::isPointInsideFast now using some epsilon to catch all points on the borders.
- triangle3d::getIntersectionOfPlaneWithLine calculates now with higher precision for more exact results.
- triangle3d::isOnSameSide (used by isPointInside) calculates now with higher precision and uses some epsilon to make it work with larger integers and less floating point troubles. Slightly slower now.

Fix time for animated model in anti-aliasing test (we should kick out animations from such tests completely!). Results still not as in reference image, but model is anti-aliased. Lines not anti-aliased at value 2 (starts around 10 here). I suspect that's too much driver dependent. Increased requiredMatch to 99.4 as animation might have been reason for low test-value - decrease again if it still fails on other system and is really OK.

- fast_atof tests now running on 64-bit (should've been last 64-bit specific trouble in tests).


git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@4180 dfc29bdd-3216-0410-991c-e03cc46cb475

- Allow difference of 1 ULP in fast_atof tests (as that is still correct). Note that this only fixes part of the fast_atof test, the whole tests still fails on 64-bit because test_strtol still fails (that looks more like a real bug).

Test ioScene needed time set to the number of the beast to work (I'm not joking man!). Works now independent of computer speed (but should probably use an updated irr file sooner or later - is this from irrEdit as the format looks outdated?).
Remove unused variables in billboards test and testUtils.
