History (should go into ResourceCompilerImage.History):
* 04/03/2008 MartinM: added highpass feature, fixed border handling in mip generation, 
* 04/24/2008 MartinM: added /help to log all keys with their help, added multiline support for the help text 





todo:
* center on dual monitor
* prepare useful templates
* SRF file format
* apply bump to srf file
* propose format with alpha is alpha is present
* mem preview is wrong if mip==0
	
	
	
* reduce resolution with add and sub
* presets
* platform settings (low mem, compressed normalmaps, high quality version, ...)
* apply greyscale bumpmap to normalmap
* D3DXComputeNormalMap
* directory specific parameters
* close window = cancel
* non power of two warning
* check for resource compiler (is gfx support enougth)
* Init() with access to log, error and info



future todo:
* gamma, brightness
* support premultiplied alpha (DXT2 and DXT4)
* 8bit, 4bit indexed colors (with or without luminance)
* statistics (frequency)
* ifdef for localization and special versions
* mask color for lightmaps and border colors
* better mipmap filter kernel
