* ==== == ======
|
|
* 03/11/95 stevela Initial revision.
|
|
* servank
|
|
* 04/11/95 stevela Context added to call blocks.
|
|
* Materials added. Required as lighting references
|
|
* handles.
|
|
* SetViewportData HAL function added.
|
|
* 10/11/95 stevela Pack structures for driver -p4 option...
|
|
* 11/11/95 stevela Remove definition of D3DHALCreateDriver.
|
|
* Add lpDDSZ to D3DHAL_CONTEXTCREATEDATA.
|
|
* Definition of lpLocalVertexBuffer changed to
|
|
* LPD3DTLVERTEX.
|
|
* 07/12/95 stevela Added texture swapping.
|
|
* 18/12/95 stevela Added GetState and GetMatrix.
|
|
* 17/02/95 stevela Use execute buffers for tl and h vertex buffers
|
|
* 23/02/95 dougrab Change all handles to DWORD
|
|
* 02/03/96 colinmc Minor build fix
|
|
* 17/04/96 stevela Use ddraw.h externally and ddrawp.h internally
