64e6124f27 glamor: move GL_OES_EGL_image check next to EGL_EXT_image_dma_buf_import
We're using the former only as the latter is present. Thus in some cases
we might incorrectly error out if it's missing.

Namely - glamor_glx, glamor_egl without gbm, EGL_KHR_gl_texture_2D_image
or EGL_EXT_image_dma_buf_import.

Fixes 58d54ee82df(glamor: explicitly check for GL_OES_EGL_image)

ea03e314f9 glamor: Don't try to free the pixmap priv if we fail to allocate FBO.
Fixes a regression since a2a2f6e34b.  I
missed this in testing on x86, because we never fail to allocate an
FBO.  We do hit this path on VC4, though.

80b6652c9f glamor: Drop a bunch of glamor_priv == NULL checks.
Now that it's always non-null when the pixmap is non-null, we don't
need so much of this.  glamor_get_pixmap_private() itself still
accepts a NULL pixmap and returns NULL, because of glamor_render.c

a2a2f6e34b glamor: Ask the server to always allocate our private.
This avoids a lot of screwing around to attach our privates later.  It
means that non-glamor pixmaps now gain 120 bytes of glamor privates on
64-bit (which has quite a bit of fixable bloat), and glamor pixmaps
take one less pointer of storage (not counting malloc overhead).

Note that privates start out zero-filled, which matches the callocs we
were doing when making our own privates, and in the case of an fb
pixmap that has a priv where it didn't before, the type ends up being
GLAMOR_MEMORY as we would want.

v2: Clarify that the GLAMOR_MEMORY enum must be 0 (as it was
    previosuly), so that the new pixmap private behavior is as
    expected.  Suggested by keithp.

b0d2e01031 glamor: Replace CompositeGlyphs code [v2]
New composite glyphs code uses the updated glamor program
infrastructure to create efficient shaders for drawing render text.

Glyphs are cached in two atlases (one 8-bit, one 32-bit) in a simple
linear fashion. When the atlas fills, it is discarded and a new one
constructed.

v2: Eric Anholt changed the non-GLSL 130 path to use quads instead of
two triangles for a significant performance improvement on hardware
with quads. Someone can fix the GLES quads emulation if they want to
make it faster there.

v3: Eric found more dead code to delete

5064ffab63 glamor: Always destroy EGL image associated with destroyed pixmap
There were three paths that called eglDestroyImageKHR:

 * The front buffer
 * The intel driver's flip buffer
 * pixmaps under DRI3

This patch unifies the second two by having glamor_destroy_pixmap
always destroy any associaged EGL image. This allows us to stop
storing the back_pixmap pointer in glamor as that was only used to
make sure that buffer was freed at server reset time.

65cc0982af glamor: Don't insert fbos from external objects into fbo cache
Mark fbos created from external buffers so that when the associated
pixmap is destroyed, they aren't put into the fbo cache for later
re-use and are instead freed immediately.

7e6bd54684 glamor: Remove shader-based trapezoid implementation. Fixes Bug 76213.
I can't find any performance benefit to using the GL path and the code
renders this trapezoid incorrectly:

  		                 top: FIXED   29.50
		              bottom: FIXED   30.00
		            left top: POINT    0.00,   29.50
		         left bottom: POINT    0.00,   30.50
		           right top: POINT -127.50,   29.50
		        right bottom: POINT   52.50,   30.00

This should render a solid line from 0,30 to 52,30 but draws nothing.

The code also uses an area computation for trapezoid coverage which
does not conform to the Render specification which requires a specific
point sampling technique.

d18f5801c9 glamor: Add glamor_program based 0-width dashed lines
This makes sure the pixelization for dashed lines matches non-dashed
lines, while also speeding them up.

v2: Switch to glamor_make_current

v3: Create dash pattern pixmap without GLAMOR_CREATE_FBO_NO_FBO

v4: Adopt suggestions from Eric's review:

  - Drops power-of-two alignment of our line vertex data, simplifying
    the code.

  - Stops reading from the VBO.  While on keithp's and my machines the
    VBO is mapped cached, on many implementations it will be mapped WC,
    making those reads extremely expensive.

  - Style fixes (line wrapping, spaces around operators).

v5: Adopt suggestions from Markus' review:

  - Use max when computing zero-width dashed line length.

    Don't open code max here.

  - Embed CoordModePrevious into VBO writing for dashed lines

    Instead of pre-computing the coord mode previous results, just
    embed this in the loop which fills the vertex buffer. Saves
    re-writing the request buffer, and shortens the code a bit

v6: Export glamor_destroy_gc for UXA

    UXA needs to call glamor_destroy_gc from its GCFuncs, so export
    it.

45ebc4e3fa glamor: Add glamor_program based copy acceleration
Paints with textures, using a temporary buffer for overlapping copies

Performs CPU to GPU transfers for pixmaps in memory. Accelerates copy
plane when both objects are in the GPU. Includes copy_window
acceleration too.

v2: Use NV_texture_barrier for non-overlapping copies within the same
drawable

v3: Switch to glamor_make_current

v4: Do overlap check on the bounding box of the region rather than
    on individual boxes

v5: Use Eric Anholt's re-written comments which provide a more accurate
    description of the code

v6: Use floating point uniform for copy plane bit multiplier. This
    avoids an int to float conversion in the copy plane fragment shader.

    Use round() instead of adding 0.5 in copy plane. round() and +0.5
    end up generating equivalent code, and performance measurements
    confirm that they are the same speed. Round() is a bit clearer
    though, so we'll use it.

15e4d14dfa glamor: Replace fallback preparation code
These offer a simpler and more efficient means for temporarily
transitioning to CPU-accessible memory for fallback implementations.

v2: Do not attempt fallbacks with GLAMOR_DRM_ONLY pixmaps

    glamor cannot transfer pixels for GLAMOR_DRM_ONLY pixmaps using
    glReadPixels and glTexSubImage2D, and so there's no way to perform
    fallback operations with these pixmaps.

v3: Clear ->pbo field when deleting the PBO.  Otherwise, we'd reuse
    the old name next time we fall back on the pixmap, which would
    potentially conflict with some other pixmap that genned a new
    name, or just do a lazy allocation of the name (compat GL context,
    like we currently use) or error out (core GL context, like we hope
    to use some day).  Also, style fixes.  Changes by anholt, acked by
    keithp.
