It was only implemented in the swrast driver and probably not used by
any applications. A modern app would use a dependent/chained texture
lookup in the fragment shader.
|
|
This was sometimes useful back when 16-bit framebuffers were prominent.
|
|
This adds i965 support for GL_EXT_framebuffer_sRGB, it introduces a new
constant to say that the driver can support sRGB enabled FBOs since enabling
the extension doesn't mean the driver can actually support sRGB.
Also adds the suggested state flush in the core code suggested by Brian.
fix the ARB_fbo color encoding.

This adds the get/enable enums and internal gl_config storage
for this extension.
In theory this is all that is needed to enable this extension
from what I can see, since its not mandatory to implement the
features if you don't advertise the visuals or the fb configs.

This is only used in the i915 driver where it provides little benefit
for very few applications that use it with fixed function TNL.
|
|
More optional code.
|
|
Another optional ARB_imaging subset extension.
|
|
This has always been optional, and not useful.

|
Use a goto instead of replicating the _mesa_error() call many times.
enable.o is about 15% smaller.

ctx->Color.BlendEnabled is now a GLbitfield instead of a GLboolean to
indicate blend on/off status for each color/draw buffer.
This is infrastructure for GL_EXT_draw_buffers2 and OpenGL 3.x
New functions include _mesa_EnableIndexed(), _mesa_DisableIndexed(), and
_mesa_IsEnabledIndexed(). The enable function corresponds to
glEnableIndexedEXT() for GL_EXT_draw_buffers2 or glEnablei() for GL3.
Note that there's quite a few tests for ctx->Color.BlendEnabled != 0 in
drivers, etc. Those tests can remain as-is since the mask will be 0 or ~0
unless GL_EXT_draw_buffers2 is enabled.

At the time of the enable there may not be a Z buffer, but one
may be attached to the FBO later.
|
|
If the currently bound FBO isn't yet validated it's possible for
rgbMode to be zero so we'll lose the texture enable.
This could fix some FBO rendering glitches, but I don't know of
any specific instances.
|
|
Fixed gallium build breakage.
|
|
This currently doesn't include fixing up the cliptests in the assembly
paths to support ARB_depth_clamp, so enabling depth_clamp forces the C path.
|
|
|
|
|
|
|
|
This was never fully fleshed out and hasn't been used.
|
|
With FBOs one could enable stencil before a stencil buffer is later bound.

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.

One could enable depth testing before binding an FBO that has a depth buffer
so this test is no longer useful or correct.

The max texture coord units is still 8. All the fixed-function paths are
still limited to 8 too. But GLSL shaders can use more samplers now.
Note that some texcoord-related data structures are declared to be 16
elements in size rather than 8. This just simplifies the code in a few
places; the extra elements aren't accessible to the user.
These changes haven't been extensively tested yet, but sanity checking has
been done.
It should be possible to increase the max image units/samplers to 32 without
doing anything special. Beyond that we'll need longer bitfields in a few
places.

A first attempt at moving gallium onto a branch directly off master...
It will be interesting to see how much work this takes to get running.
Have resolved the conflicts semi-arbitarily, not compiled or tested.

Basically, the application enables client vertex and color arrays,
renders something, then disables color array, and renders something
else (using vertex array only). Even though the color array is
disabled (and the pointer is no longer valid), the driver still tries
to read color data from this array (which results in an exception).
This is because enabling/disabling array does not trigger
_ae_update_state() and the list of enabled arrays is not updated.
_ae_update_state() it's called on the first state validation only (as
all the "dirty" flags are set at the beginning). Any further change to
client arrays' state has no effect.

Shadow sampling from texture arrays is still not implemented. Everything
else should be there, though.

Fix bug inserted in commit c9e723e5013443df984cb3987ffa3a9ba3384b89.
