There was a bug that existed in open GL ES 2.0 implementations and random textures

[hibengler]

where glTexImage2D could not convert GL_RGB formed textures into GL_RGBA
while generating the noise textures. The GL error
was GL_INVALID_OPERATION(0x502)
This probably made the noise textures blank.
So a new class was added that has the alpha channel for the values.

Also - added a hook so that the time of day can be manipulated in case milkdrop is being used for non-real time rendering. This hook is not implemented on WIN32 variants.

i truly actually have no idea what is going on here. comment? make some constants?

[hibengler]

No, it is generating random noise data used by some of the visualizers.

The noise functions convert the standard random numbers to follow different
ranges, styles, etc.

inline float noise looks to be generating a psuedo random number that is seeded with X.

This file is basically a copy of PerlInNoise.hpp, and does the same thing as PerlInNoise class, except that it generates the noise in an RGBA buffer instead of an RGB buffer.

OpenGL ES 2.0 cannot transform RGB into RGBA in hardware, but it can do RGBA to RGBA. This is why I me the step-sibling class.

you can merge master in to (hopefully) get tests to pass - i just made some fixes

The windows build still appears to be failing

I think I got it. Unable to test on win32 so I reverted that section in timer.h (and cpp) to what it was.

Thanks for the effort! Appreciate it.

Fixed projectM_SDL_main.cpp for windows platforms.
