Adds functions:

`PixelGlow_Start(frame[, color[, N[, frequency[, length[, th[, xOffset[, yOffset[, border[ ,key]]]]]]]])`

Starts glow over target frame with set parameters:

- frame - target frame to set glowing;
- color - {r,g,b,a}, color of lines and opacity, from 0 to 1. Defaul value is {0.95, 0.95, 0.32, 1};
- N - number of lines. Defaul value is 8;
- frequency - frequency, set to negative to inverse direction of rotation. Default value is 0.25;
- length - length of lines. Default value depends on region size and number of lines;
- th - thickness of lines. Default value is 2;
- xOffset,yOffset - offset of glow relative to region border;
- border - set to true to create border under lines;
- key - key of glow, allows for multiple glows on one frame;

`PixelGlow_Stop(frame[, key])`

Stops glow with set key over target frame

`AutoCastGlow_Start(frame[, color[, N[, frequency[, scale[, xOffset[, yOffset[, key]]]]]]])`

Starts glow over target frame with set parameters:

- frame - target frame to set glowing;
- color - {r,g,b,a}, color of particles and opacity, from 0 to 1. Defaul value is {0.95, 0.95, 0.32, 1};
- N - number of particle groups. Each group contains 4 particles. Defaul value is 4;
- frequency - frequency, set to negative to inverse direction of rotation. Default value is 0.125;
- scale - scale of particles;
- xOffset,yOffset - offset of glow relative to region border;
- key - key of glow, allows for multiple glows on one frame;

`AutoCastGlow_Stop(frame[, key])`

Stops glow with set key over target frame


Blizzard glow is based heavily on https://www.wowace.com/projects/libbuttonglow-1-0

`ButtonGlow_Start(frame[, color[, frequency]]])`

Starts glow over target frame with set parameters:

- frame - target frame to set glowing;
- color - {r,g,b,a}, color of particles and opacity, from 0 to 1. Defaul value is {0.95, 0.95, 0.32, 1};
- frequency - frequency. Default value is 0.125;
- frameLevel - frameLevel. Default value is 8;

`ButtonGlow_Stop(frame)`

Stops glow over target frame
