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. | |
