* mesa: replace gl_context->Multisample._Enabled with ↵Bas Nieuwenhuizen2016-03-241-0/+3
| | | | | | | | | | | | _mesa_is_multisample_enabled. This removes any dependency on driver validation of the number of framebuffer samples.

* main: Use a derived value for the default sample countNeil Roberts2016-02-051-1/+2
| | | | | | | | | | | | | | | | | Previously the framebuffer default sample count was taken directly from the value given by the application. On the i965 driver on HSW if the value wasn't one that is supported by the hardware it would hit an assert when it tried to program the state for it. This patch fixes it by adding a derived sample count to the state for the default framebuffer. The driver can then quantize this to one of the valid values in its UpdateState handler when the _NEW_BUFFERS state changes. _mesa_geometric_samples is changed to use the new derived value.

In addition, to avoid replicated code, make the function _mesa_scissor_bounding_box() use this new function.

* mesa: Move OES_read_format support from drivers into the core.Eric Anholt2009-12-091-0/+5
| | | | | | | | | | | The assertion is that the correct read type to be using is the native type of the underlying read renderbuffer. For some fallback paths, this may be worse than GL_RGBA/GL_UNSIGNED_BYTE for reads today, but it gets all drivers the expected GL_BGRA/GL_UNSIGNED_BYTE for ARGB8888 or GL_BGR//GL_UNSIGNED_SHORT_5_6_5_REV for rgb565 with no work. This fixes the intel (and other) DRI drivers to report read formats that should hit blit PBO readpixels paths.
