[Mesa-dev] [PATCH 2/2] wglinfo: query/print sRGB and float pixel format info

Print the columns in the same place as glxinfo.
Use 3 digit hexadecimal field for printing pixel format number.
Remove the 'caveat' field which is non-existant in WGL.
This also fixes a minor bug when we query WGL_PIXEL_TYPE_ARB.
We previously stored the result in info->pfd.iPixelType which is a BYTE
type but the WGL_TYPE_* values are all larger than 255. Use a temporary
variable instead.
