The current texture for any particular texture unit is given an additional
reference in update_texture_state(); but if the context is closed before
that texture can be released (which is quite frequent in normal use, unless
a program unbinds and deletes the texture and renders without it to force
a call to update_texture_state(), the memory is lost.
This affects general Mesa; but the i965 is particularly affected because
it allocates a considerable amount of additional memory for each allocated
texture.
(cherry picked from master, commit c230767d69)
The src/dest x,y, and w,h arguments of the pipe->surface_copy
function are unsigned and the drivers aren't expecting negative
(or extremly-large unsigned) values as inputs. Trim the requests
at the state-tracker level before passing down.
Add a new flag mvp_with_dp4 in the context, and use that to switch
both ffvertex.c and programopt.c vertex transformation code to
either DP4 or MUL/MAD implementations.
This is a quick fix for z fighting in quake4 caused by the mismatch
between vertex transformation here and in the position_invarient code.
Full fix would be to make this driver-tunable and adjust both
position_invarient and ffvertex_prog.c code to respect driver
preferences.
Add a dummy function which exists only so that tgsi_text_translate()
doesn't get magic-ed out of the libtgsi.a archive by the build system.
Don't remove unless you know this has been fixed - check on
mingw/scons builds as well.
Previously we created the pipe_surface during framebuffer validation.
But if we did a glCopyTex[Sub]Image() before anything else we wouldn't yet
have the surface. This fixes that.
When building mangled Mesa on Darwin, the exported symbols are
named `_mgluWhatever' instead of simply `_gluWhatever'. When
using a list of exported symbols via the system ld's
`-exported_symbols_list' command line option (as done by mklib),
this resulted in error messages about exporting symbols which do
not exist.
Fortunately the file format accepts simple wildcards. This throws
a wildcard so that the symbol list will match both the mangled and
non-mangled names, preventing the warning and actually exporting
the correct symbols in one shot.
