xfree86: Provide backward-compatibilty API for OdevAttributes
This allows drivers to compile using the old OdevAttributes API
against a new server. It generates compiler errors if the caller uses
the wrong or undefined attribute types, or if the caller provides an
incorrect default value for an integer attribute.

config: Replace OdevAttributes linked list with struct
OdevAttributes are a fixed set of values with known types; instead of
storing them in a linked list and requiring accessor/settor functions,
replace the list header, struct OdevAttributes, with a struct that
directly contains the values. This provides for compile-time
typechecking of the values, eliminates a significant amount of code
and generally simplifies using this datatype.

xephyr: Allow initializing glamor with gles2 (on GLX).
This should be useful for glamor development, so you can test both
paths (which are significantly different, and apparently
glamor_gradient.c was broken on GLES2 as of the import).

glamor: Share code for put_image handling.
The difference between the two is that XF86 has the clip helper that
lets you upload less data when rendering video that's clipped. I
don't think that's really worth the trouble, especially in a world of
compositors, so I've dropped it to get to shared code.
It turns out the clipping code was broken on xf86-video-intel anyway.
To reproduce, run without a compositor, and use another window to clip
the top half of your XV output on the glamor XV adaptor: the rendering
got confused about which half of the window was being drawn to.

kdrive: Mark XV names const to avoid warnings.
No code modifies it at runtime, and it's common to store string
literals to it.

glamor: Split the XV code into XF86-dependent parts and generic.
I want to expose this from Xephyr as well, both to be able to test XV
changes rapidly, and beause the XV passthrough to the host's overlay
really doesn't work out well when we glXSwapBuffers() over the
colorkey.

commit 18c09e60bf16b28060ade5d24110f2aa6bc19b57
Author: Keith Packard <keithp at keithp.com>
Date: Sun Mar 16 20:49:28 2014 -0700
glamor: Replace glamor_solid_boxes and glamor_solid with GC using code
This provides glamor_solid_boxes and glamor_solid using regular GC
operations instead of calling directly to underlying rendering
functions. This will allow the old rendering code to be removed.

commit bd3b2c48f69a5169aefb261c041462271c69a07a
Author: Keith Packard <keithp at keithp.com>
Date: Thu Apr 3 14:22:52 2014 -0700
glamor: Add accelerated stipple support
This copies the stipple to a 8bpp pixmap and uses that to paint the
texture from.
v2: Create deep stipple pixmap without GLAMOR_CREATE_FBO_NO_FBO
v3: Fix stipple origin sign (matches tiles now). Track changes
to original stipple with damage. This isn't required by the
X spec, but java appears to depend on it, so we'll just do it.
When Glamor switches to 8bpp bitmaps, we'll be able to render
directly from them and not need this anymore.
v4: Review comments from Eric:
* Remove stray whitespace change
* Avoid "large" pixmap for stipple by using GLAMOR_CREATE_NO_LARGE
* Wrap to 80 columns
v5: Don't crash when stipple damage tracker is destroyed
The stipple damage tracker is automatically destroyed when the
associated stipple pixmap is destroyed. When this happens, just
clear the pointer from the GC rather than calling
glamor_invalidate_stipple; that function would call
DamageUnregister on the now invalid stipple damage pointer and
crash.

commit d18f5801c9a632dd4d9f8b7912491b6623e943d5
Author: Keith Packard <keithp at keithp.com>
Date: Wed Apr 2 14:07:20 2014 -0700
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.

commit dc9fa9080a1cb994b4e54a341d2245f442dac576
Author: Keith Packard <keithp at keithp.com>
Date: Sun Mar 23 20:59:02 2014 -0700
glamor: Use glamor_program and GL_LINES for 0-width lines
GL lines are nearly X compliant; you just need to fill in the last
pixel when the client hasn't requested CapNotLast.
v2: switch to glamor_make_current
v3: use miPolylines instead of custom glamor fallback path. Wrap
code to 80 columns.

commit 45ebc4e3fac7f1a85167d05e2833949b89f02d64
Author: Keith Packard <keithp at keithp.com>
Date: Sat Mar 15 13:31:18 2014 -0700
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.

commit 15e4d14dfae054c026b7e965ac33985e5cf6a168
Author: Keith Packard <keithp at keithp.com>

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.

mi: Draw multiple lines in one FillSpans call in miZeroLine
miZeroLine allocates enough space to draw a line spanning the entire
width/height of the target drawable. When drawing multiple shorter
lines, this leaves most of the space in that buffer unfilled. Let
multiple lines be drawn into the buffer if there is plenty of space.
Speeds up glamor fallback zero-width lines:
Before
6000000 trep @ 0.0020 msec (508000.0/sec): 1-pixel line
6000000 trep @ 0.0020 msec (492000.0/sec): 10-pixel line
6000000 trep @ 0.0023 msec (427000.0/sec): 100-pixel line
4000000 trep @ 0.0035 msec (282000.0/sec): 500-pixel line
After:
600000000 trep @ 0.0000 msec (43400000.0/sec): 1-pixel line
140000000 trep @ 0.0001 msec (13000000.0/sec): 10-pixel line
16000000 trep @ 0.0008 msec (1300000.0/sec): 100-pixel line
4000000 trep @ 0.0038 msec (261000.0/sec): 500-pixel line
(500 pixel lines do not change in performance because the buffer can
only one one of them.)

mi: Fill spans for multiple arcs in miPolyFillArc
This allocates span data for multiple arcs and draws the
whole set in one call, rather than doing them one at a time. For
modern hardware, this is a significant performance improvement.
v2: Limit the number of spans per buffer to 4M to avoid
integer overflow in computing the malloc size.

mi: Make miPolyArc draw fast zero-width when possible
Instead of forcing drivers to figure out when to call miZeroPolyArc,
have miPolyArc call that when possible.
This involved renaming the existing miPolyArc call to miWideArc and
creating a new miPolyArc wrapper function as miZeroPolyArc falls back
to miWideArc when the arc is too large to be drawn with the zero-width
code (ellipses larger than 800x800).

Instead of requiring all drivers to figure out which mi function to

handles them correctly. Now drivers can simply use miPolylines in all
cases.
