Glenn Maynard a62788fb9f Split out tween weighting functions. Add tweening from 1d and 2d 
bezier curves.

The "bouncebegin" and "bounceend" tweens are now implemented in Lua,
using 2D beziers which approximate the old behavior very closely.
Added "ease" tween, which works like Flash's.

Custom tweens can be used, passing in a table of 4 values for a
1D bezier, or 8 values for 2D.

   tween,.5,TweenBezier,{ 0, p1, p2, 1 }
   tween,.5,TweenBezier,{ 0, 0, x1, y1, x2, y2, 1, 1 }

As with all tweens, the first parameter is the duration.

The 1D bezier { a, b, c, d } is equivalent to the 2D bezier
{ 0, a, 1/3, b, 2/3, c, 1, d }, but a 1D bezier is more efficient.

Glenn Maynard a56b7ac59b Declare these as const functions, like sinf and cosf. This fixes the compiler 
not optimizing calls to these as well as sinf/cosf.

Chris Danford 32c3953726 "scale, rotate, translate", not "rotate, scale, translate". It's amazing that this is a day 1 bug. 2005-07-25 17:57:42 +00:00

Glenn Maynard 944bba77b6 I don't remember what RageMatrixCommand was for. Remove it. 2005-02-05 03:15:40 +00:00
Glenn Maynard 3e389c103b Translation and scaling (when applied in that order) are trivially combined; 
save a matrix multiply for every actor.  (Maybe we can avoid doing any,
for objects which are neither rotated nor scaled--such as those positioned
based on their parent--but I'm not sure it's worth it.)  Rotations can be
combined without doing a full matrix multiply, too; if an actor rotates at all,
only do one matrix multiply.

don't return by value)

Chris Danford a75cd6e7b1 Fix D3D z-buffer problem by having separate GetOrthoMatrix functions for OGL and D3D. 
I don't understand why the two APIs create an ortho matrix so differently, but I'm tried of messing with it for now.

Glenn Maynard 2d7b9001b1 cleanups; remove commented out stuff that's not needed; fix broken 
friend function (it's to make 3 * RageColor/Vector work like RageColor * 3,
but I don't know if anything uses it.)
