| 1029 | It is possible for an X11 frame buffer to advertise a |
| 1030 | PseudoColor visual, but to force all allocated colormap |
| 1031 | entries to be gray colors. The Dome card does this when the |
| 1032 | HW is jumpered for a grayscale monitor, but the default |
| 1033 | visual is set to PseudoColor. In that case awtJNI_GetColorModel |
| 1034 | will be called with aData->awtImage->clrdata.grayscale == 0, |
| 1035 | but the IndexColorModel created below will detect that only |
| 1036 | gray colors exist and expect the inverse gray LUT to exist. |
| 1037 | So above when filling the hR, hG, and hB arrays we detect |
| 1038 | whether all allocated colors are gray. If so, but |
| 1039 | aData->awtImage->clrdata.grayscale == 0, we fall into this |
| 1040 | code to set aData->awtImage->clrdata.grayscale = 1 and do |
