QueryInterface should return S_OK on success and set the object
pointer to NULL on failure. This is similar to the patch Ivan
submitted a while ago for wined3d.
Let the few existing parts which need the capabiliteis use the WineD3D
capability structure (gl_info). This info structure contains next to
'flags' inidicating certain features also all GL/GLX functions
pointers. Because D3D8 moves over to the wined3d gl_info structure all
the gl prototypes in d3dcore_gl.h were unneeded and removed.
the interface but it is more correct way (Microsoft even have a
resource type of volume).
- Moved usage, format, allocatedMemory and size onto the resource
class structure.
- Refactored Preload for classes that inherit BaseTexture, preload now
binds the texture instead of bind texture calling preload, bindTexture
allocated a glTexture if there isn't one.
- Added two new class static members BaseTexture_CleanUp and
Resource_CleanUp that should be called by classes that implement
BaseTexture or Resource.
- Move some of the screen mode related functions into wined3d and add
untested support for the new d3d9 options of providing the format to
some of the calls.
- Move other functions from the directx interface into the common
library and implement the calls from d3d9 as well.
- Copy across the first of the functions used to make traces more readable,
creating utils.c to store them in. Eventually the ones in d3d8 will be
removed but for now just duplicate the code.
constants (the Mesa bug) and VRally use the 0..95 indexes so fix it
- fix normalize for some HW VertexShader inputs
- trying to fix the combination of NV_texture_combine_4 with
texture_combine_EXT (impl of D3DTOP_DISABLE, D3DTOP_MODULATE for
NV_texture_combine_4)
- if shaders disabled declare to support 0 for MaxVertexShaderConst.
- add a new DEBUG_SINGLE_MODE #define (for debug caps needs)
- better traces for surface dumping
- much better Texture support on Utilities functions and on
CheckDeviceType
- D3DRS_ZVISIBLE as unsupported (as seen in msdn)
