rendering, not just when rendering to a texture.  Otherwise, if a FBO
consists of a mix of textures and renderbuffers the up/down orientation

15 years agomesa: fix a render to texture FBO validation bug
Brian Paul [Thu, 29 Jan 2009 16:20:18 +0000 (09:20 -0700)]
mesa: fix a render to texture FBO validation bug

When glTexImage() is called we need to re-validate any FBOs that point to
the texture (i.e. render-to-texture) since changing the texture's size/format
will effect FBO completeness.

We don't keep a list of all FBOs rendering into each texture (which would be
a bit messy) so we check all FBOs in existance.  To optimize this, the
gl_texture_object->_RenderToTexture flag is used to avoid checking textures
that have never been used as renderbuffers.  So, we only walk over all FBOs
(there's usually only a few) when glTexImage() modifies a RTT texture.

Fixes a bug seen in shadowtex.c when toggling packed depth/stencil mode.

Track separate back-face stencil state for OpenGL 2.0 /
GL_ATI_separate_stencil and GL_EXT_stencil_two_side.  This allows all
three to be enabled in a driver.  One set of state is set via the 2.0
or ATI functions and is used when STENCIL_TEST_TWO_SIDE_EXT is
disabled.  The other is set by StencilFunc and StencilOp when the
active stencil face is set to BACK.  The GL_EXT_stencil_two_side spec has
more details.
