To understand this patch, let's start at the protocol interface where
the relationship between the coordinate spaces is documented:
static Bool
_glamor_composite(CARD8 op,
PicturePtr source,
PicturePtr mask,
PicturePtr dest,
INT16 x_source,
INT16 y_source,
INT16 x_mask,
INT16 y_mask,
INT16 x_dest, INT16 y_dest,
CARD16 width, CARD16 height, Bool fallback)
The coordinates are passed to this function directly off the wire and
are all relative to their respective drawables. For Windows, this means
that they are relative to the upper left corner of the window, in
whatever pixmap that window is getting drawn to.
_glamor_composite calls miComputeCompositeRegion to construct a clipped
region to actually render to. In reality, miComputeCompositeRegion clips
only to the destination these days; source clip region based clipping
would have to respect the transform, which isn't really possible. The
returned region is relative to the screen in which dest lives; offset by
dest->drawable.x and dest->drawable.y.
What is important to realize here is that, because of clipping, the
composite region may not have the same position within the destination
drawable as x_dest, y_dest. The protocol coordinates now exist solely to
'pin' the three objects together.
extents->x1,y1 Screen origin of clipped operation
width,height Extents of the clipped operation
x_dest,y_dest Unclipped destination-relative operation coordinate
x_source,y_source Unclipped source-relative operation coordinate
x_mask,y_mask Unclipped mask-relative operation coordinate
One thing we want to know is what the offset is from the original
operation origin to the clipped origin
Destination drawable relative coordinates of the clipped operation:
x_dest_clipped = extents->x1 - dest->drawable.x
y_dest_clipped = extents->y1 - dest->drawable.y
Offset from the original operation origin:
x_off_clipped = x_dest_clipped - x_dest
y_off_clipped = y_dest_clipped - y_dest
Source drawable relative coordinates of the clipped operation:
x_source_clipped = x_source + x_off_clipped;
y_source_clipped = y_source + y_off_clipped;
Mask drawable relative coordinates of the clipped operation:
x_mask_clipped = x_source + x_off_clipped;
y_mask_clipped = y_source + y_off_clipped;
This is where the original code fails -- it doesn't subtract the
destination drawable location when computing the distance that the
operation has been moved by clipping. Here's what it does when
constructing a temporary source picture:
temp_src =
glamor_convert_gradient_picture(screen, source,
extent->x1 + x_source - x_dest,
extent->y1 + y_source - y_dest,
width, height);
...
x_temp_src = -extent->x1 + x_dest;
y_temp_src = -extent->y1 + y_dest;
glamor_convert_gradient_picture needs source drawable relative
coordinates, but that is not what it's getting; it's getting
screen-relative coordinates for the destination, adjusted by the
distance between the provided source and destination operation
coordinates. We want x_source_clipped and y_source_clipped:
x_source_clipped = x_source + x_off_clipped
= x_source + x_dest_clipped - x_dest
= x_source + extents->x1 - dest->drawable.x - x_dest
x_temp_src/y_temp_src are supposed to be the coordinates of the original
operation translated to the temporary picture:
x_temp_src = x_source - x_source_clipped;
y_temp_src = y_source - y_source_clipped;
Note that x_source_clipped/y_source_clipped will never be less than
x_source/y_source because all we're doing is clipping. This means that
x_temp_src/y_temp_src will always be non-positive; the original source
coordinate can never be strictly *inside* the temporary image or we
could have made the temporary image smaller.
x_temp_src = x_source - x_source_clipped
= x_source - (x_source + x_off_clipped)
= -x_off_clipped
= x_dest - x_dest_clipped
= x_dest - (extents->x1 - dest->drawable.x)
Again, this is off by the destination origin within the screen
coordinate space.
The code should look like:
temp_src =
glamor_convert_gradient_picture(screen, source,
extent->x1 + x_source - x_dest - dest->pDrawable->x,
extent->y1 + y_source - y_dest - dest->pDrawable->y,
width, height);
x_temp_src = -extent->x1 + x_dest + dest->pDrawable->x;
y_temp_src = -extent->y1 + y_dest + dest->pDrawable->y;

GetGlyphs is supposed to always return the full list of characters
when there is a default character available. However, if an
application opens a 16-bit two dimensional font and then draws with
8-bit requests, the bitmapGetGlyphs function in libXfont versions up
through 1.4.7 will return zero glyphs if there is no 0th row.
While this is a bug in libXfont and should be fixed there, it's easy
to protect glamor from it by simply falling through to the case that
handles GetGlyphs failures for fonts without a default character.

There were actually two issues with the original code I believe, the
first is that the call to glamor_convert_gradient_picture wasn't
properly referencing the coordinates of the source/mask pictures. The
second, was that the updated references (x_temp/y_temp) were also
improperly set, they should always be 0 because the temp pictures are
new ones that start at (0, 0). The reason it worked in certain cases
and it didn't in others (notably the tray icons) was due to the
numbers working out based on the call to glamor_composite. In the
cases that it did work extent->x1 would equal x_dest and extent->y1
would equal y_dest, making it so what was actually passed into
glamor_convert_gradient_picture and the settings for x_temp/y_temp
were correct. However, for the case when extent->x1 wouldn't equal
x_dest and extent->y1 wouldn't equal y_dest (for example with the tray
icons) then the wrong parameters get passed into
glamor_convert_gradient_picture and x_temp/y_temp are set improperly.
Fixes issues with tray icons not appearing properly in certain cases.
