| 27 | * Revision 1.2 2002/04/23 18:23:32 kschultz |
||
| 28 | * Fix up alpha buffer handling for Windows. |
||
| 29 | * - add two new Pixel Format Descriptors that do not have alpha bits to |
||
| 30 | * mirror the two that do. |
||
| 31 | * - add logic to wglChoosePixelFormat to match PFD's with respect to alpha. |
||
| 32 | * - Create/clear software alpha buffer as required. |
||
| 33 | * Now a wgl or GLUT program can control the creation of a software alpha |
||
| 34 | * buffer via the PFD or GLUT parms, respectively. |
