Call it from in the main Mesa glTexImage functions.
|
|
Just call ctx->Driver.CompressedTextureSize() when we need to get
the compressed image size.
|
|
Use _mesa_is_format_compressed() instead.
|
|
Now gl_texture_image::TexFormat is a simple MESA_FORMAT_x enum.
ctx->Driver.ChooseTexture format also returns a MESA_FORMAT_x.
gl_texture_format will go away next.
|
|
As shown in mfeatures.h, this allows users of convolve.h to work without
knowing if the feature is available.
|
|
|
|
Per the suggestion in the Intel driver, move the calls to
ctx->Driver.GenerateMipmap() into core Mesa so that drivers don't
have to worry about it.

This will make some subsequent changes easier...

All the glGetTexImage code is in one file now.

This commit adds a function to clear a texture object such that there is
no image data associated with it, and a function to dirty it so that it
will be re-tested for completeness.

Somehow this code wound up inside a comment a while back.

Fixes leak running compiz with direct rendering.

We need to make sure the framebuffer state is up to date to make sure we
read pixels from the right buffer when doing a texture image copy.
|
|
This is a (partial) backport of the signed texture format support in OGL 3.1.
Since it wasn't promoted from an existing extension roll our own.

add new entrypoints, new texture format, etc
translate in texenvprogram.c for drivers using the mesa-generated tex env
fragment program
also handled in swrast, but not tested (cannot work due to negative texel
results not handled correctly)
|
|
Use loops to consolidate lots of texture object code.

This is the big merge of the gallium-0.2 branch into master.
gallium-master-merge was just the staging area for it.
Both gallium-0.2 and gallium-master-merge are considered closed now.

Fixes failed assertion / segfault for particular proxy texture tests.

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.

Do it after initial error checking, after we know the texture's internal format.

Makes things consistant with the code in teximage.c.
We only want to apply convolution to color formats (not depth/index formats)

The ARB extension is a superset of the older SGIX extension. Any
hardware that can support the SGIX version can also support the ARB
version. In Mesa, any driver that supports one also supports the
other. This unification just simplifies some bits of code.

the drivers.
This should probably be pulled into main-line Mesa...
