-If t->bottom is close to MIN_INT, removing top can wraparound, so do the check properly.

+Subject: glamor: Fix temp picture coordinates in glamor_composite_clipped_region
+
+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;
