| 20 | <para> |
| 21 | In the May, 2012 update of the OpenGL 4.2 Specification, all |
| 22 | APIs using the types GLclampf and GLclampd were modified to |
| 23 | use GLfloat and GLdouble, respectively, instead. Language |
| 24 | was added to the Specification requiring that these |
| 25 | parameters be clamped, when required, at use time rather |
| 26 | than at specification time. |
| 27 | </para> |
| 28 | <para> |
| 29 | This change allows specifying parameters in ranges |
| 30 | appropriate for non-fixed-point framebuffers (integer and |
| 31 | floating-point formats). The change does not require any |
| 32 | changes to user code calling these functions, because the |
| 33 | actual underlying types are identical, the behavior is |
| 34 | externally unchanged, and the header files continue to |
| 35 | define the old types for compatibility with older code. |
