Image_PixMap::ImgFormat - extend enumeration by ImgAlpha and ImgAlphaF. OpenGl_Workspace::setTextureParams() - specify GL_REPLACE for 1-component textures with disabled modulation. OpenGl_Texture::GetDataFormat() - return GL_LUMINANCE format for ImgGray format and GL_ALPHA for ImgAlpha. vmarkerstest - override pixel format for grayscale images to ImgAlpha. Add test case bugs/vis/bug25544_graytexture.
