05c824db87 fix some _ActualFormat initializations 2006-03-22 14:19:17 +00:00

829f6909bd Disable texture memory initialization. 
Add some missing error checks in the buffer manager.

34f1ebc72f New functions for manipulating depth/stencil renderbuffers: 
_mesa_extract_stencil(), _mesa_insert_stencil(), _mesa_promote_stencil().

c6e586ee0c Export _mesa_lookup_renderbuffer() and _mesa_lookup_framebuffer() functions. 
Use new _mesa_lookup_texture() function.

9180d932c6 New _mesa_lookup_texture() function to wrap the hashtable lookup. 2006-03-22 02:09:22 +00:00

95df1b67a2 Reorganize the code relating to updating the framebuffer's _DepthBuffer 
and _StencilBuffer fields.
These fields are often wrappers/adaptors around combined depth/stencil
renderbuffers.
Make _mesa_update_depth_buffer() and _mesa_update_stencil_buffer() public.

bc400c3f30 Lots of updates for new gl_renderbuffer ClassID and _ActualFormat fields. 
Removed hw_stencil field from context.  Now determine hw stencil from looking
at the stencil renderbuffer.
Enabled the GL_EXT_packed_depth_stencil extension.  May not be permanent but
for now it allows hw stencil to work with the fbotexture.c demo (w/ -ds flag).
Using separate renderbuffers for GL_DEPTH_ATTACHMENT_EXT and
GL_STENCIL_ATTACHMENT_EXT works, but is currently a software fallback.

3a3db0e9ec A number of renderbuffer changes: 
1. Added _ActualFormat field to record the actual storage format chosen by
   Mesa or the driver.  The InternalFormat field has to store the value that
   the user passed into the glRenderbufferStorageEXT() function.
2. Added ClassID field so driver can distinguish between gl_renderbuffers
   and intel_renderbuffers (for example).  Not very OOP-like, but seems to
   be a reasonable solution.

31a82a663c When s/w rendering to texture memory, don't invert Y as for regular rendering. 
Perhaps put yScale, yBias factors into intel_renderbuffer since they're
the same as those in intelCalcViewport().

fb440c9f82 Need to set hardware viewport params depending on window vs. FBO rendering 
and normal FBO vs. RTT.  Fixes upside down teapot in fbotexture.c demo.
Still need to adjust glDraw/Read/CopyPixels Y direction depending on if
we're doing RTT.

ec1db9db1f In intelReadBuffer() check/update framebuffer completeness. 
Added intel_get_renderbuffer() and intel_get_rb_region() helper functions
to simplify some code (should be inlined in the future).

a7cdbf5c38 Additional login in intel_draw_buffer() to check if any needed renderbuffers 
are software/fallback cases.
The hardware's combined depth/stencil buffer is now treated as such
(ala GL_EXT_packed_depth_stencil).  So the depth/stencil span functions
are effectively merged.  Renderbuffers wrappers will extract the depth or
stencil values when needed.

fe37adfde3 Added _mesa_finish_render_texture() function and reference counting for 
the renderbuffer which wraps textures.

315396ac6c Created new intel_buffers.h file with appropriate prototypes. 
Moved body of intelDrawBuffer() into new intel_draw_buffer() which will do
additional things in future.

ceee2c45cd Fixed bug in intelClearWithBlit(). If clearing multiple cliprects, the 
buffer mask was clobbered after the first rect.
Rename 'flags' to 'mask' to be consistent w/ other clearing code.

b176ef05f2 In intelCopyBuffer(), use renderbuffer regions instead of context's region 
pointers.  Added const qualifiers.  Added comments.

6d6e7a08c7 Fix up intelSwapBuffers: 
- get gl_framebuffer pointer from dPriv.
 - flush current context if bound to window we're swapping.  Previous code
   could try to flush a non-current context.
