commit 3c34dd3603989c0365654ca1b6809395c7f3b169
Author: Keith Packard <keithp at keithp.com>
Date:   Tue Apr 1 21:15:48 2014 -0700

    glamor: Add glamor_program based poly_text and image_text
    
    Accelerates text painting with GPU-based geometry computation and stippling
    
    v2: Simplify get_glyphs, expand single character variable names to
        more descriptive ones. (Markus Wick)
    v3: Rebase against the glamor_prepare_* un-renaming (changes by anholt).
    
    Improves x11perf -f8text by 417.908% +/- 11.0144% (n=10)

commit 5f700c3ac31db52f02f6ef11ea7823a8ce4f6f6f
Author: Keith Packard <keithp at keithp.com>
Date:   Tue Apr 1 21:15:47 2014 -0700

    glamor: Use glamor_program for glamor_glyphblt
    
    This constructs suitable shaders using the glamor_program
    infrastructure for poly glyph blt, and then gets rid of the no-op
    wrapper of miImageGlyphBlt.
    
    Improves x11perf -f8text by 11.6221% +/- 1.04585% (n=10)

commit 3411e8c538476443cafbb70082ef7457932e4a38
Author: Keith Packard <keithp at keithp.com>
Date:   Tue Apr 1 21:15:46 2014 -0700

    glamor: Add glamor_program based poly_fill_rect
    
    This accelerates poly_fill_rect using GPU-based geometry computation
    
    Improves x11perf -rect100 by 41.5127% +/- 7.63888% (n=10)
    Improves x11perf -rect10 by 3745.72% +/- 94.7503% (n=6)
    
    v2: Rebase on skipping the prepare rewrite for now, and fix the GLSL
        1.20 and GLES2 cases (changes by anholt).

commit 0a6d31161811c422799d6f065ea2842d42707530
Author: Keith Packard <keithp at keithp.com>
Date:   Tue Apr 1 21:15:45 2014 -0700

    glamor: Add glamor_program based fill/set/get spans
    
    This accelerates spans operations using GPU-based geometry computation
    
    -wellipse500 goes from about 4k/sec before the patch, to ~8k/sec in
    the GLES2 fallback loop, to ~100k/sec in desktop mode.
    
    v2: Rebase on skipping the prepare rewrite for now, and fix the GLSL
        1.20 and GLES2 cases (changes by anholt).

commit d78c257f523908760c1b872cc4bef3d42eb31f50
Author: Keith Packard <keithp at keithp.com>
Date:   Tue Apr 1 21:15:43 2014 -0700

    glamor: Add simple upload/download functions in glamor_transfer
    
    These use glTexSubimage2D for upload and glReadPixels for
    download. There are a variety of interfaces to the basic function as
    needed by the callers.

    glamor: Use plain GLSL 1.20 features for fill code.
    
    This prevents performance regressions from losing acceleration support
    on older hardware as we transition to using glamor_program.c for
    acceleration.

    glamor: Compute supported GLSL version and save in screen private
    
    This currently computes the GLSL version in a fairly naïve fashion,
    and leaves that in the screen private for other users. This will let
    us update the version computation in one place later on.
    
    v2: Drop an accidental rebase-squashed hunk (change by anholt).

    glamor: Bail from composite when pixmap cannot be uploaded
    
    I think the sense of the return value was just flipped here; if you
    return TRUE, then the calling code assumes that the pixmap *has* been
    uploaded and that an FBO is available. When it tries to use it, it
    crashes though. Returning false makes the caller bail back to software.

    glamor: Initialize XV shaders from glamor_xv_init instead of glamor_init
    
    The glamor_init calls to glamor_init_xv_shader were never getting run
    because GLAMOR_XV was never defined. Instead of trying to make that
    work, fix glamor_xv_init to make the call instead.
    
    Further, just get rid of the glamor_fini_xv_shader function entirely
    as the shader program will be destroyed when the context is destroyed
    at server reset time.

    glamor: glamor_poly_point_nf cannot fail for non-DDX pixmaps
    
    All of the glamor _nf functions must check to see if the DDX can
    access the pixmap directly before returning failure back to the
    driver; this restructures the point code to split out the _nf checking
    from the _gl code.

    Revert "glx: Make sure we get an FBConfig the root window's visual."
    
    This reverts commit b5a61239e2fef167c229154d7919ff862503e3f3.
    
    Not only did I screw up and introduce a warning, it turns out
    glXChooseFBConfig() explicitly ignores this attribute.  Thanks, GLX.
