2011-10-18render: export TriStrip and TriFan to the driversChris Wilson4-32/+114
Rather than perform an intermediate copy and expand the strip and the fan into a triangle list (thereby tripling the number of edges that the driver needs to process), allow the backend to hook directly into the appropriate Composite function. In order to extend the PictureScreen, without needlessly bumping the ABI, we move the existing copy implementations to mipict.c and assign those by default. To notify the ddx that the new entry points are available, we introduce PICTURE_SCREEN_VERSION.

2011-03-14Remove geometry arguments from miSourceValidate()Søren Sandmann Pedersen2-52/+17
The only user of the geometry coordinates is the software sprite code, which uses them to remove the pointer whenever the window beneath is being used as a source. However, using Window pictures as a source is extremely rare (let alone *partial* windows), so there is no harm done in just validating all of the drawable. Additionally, the miSourceValidate() function was buggy in at least three respects: (a) It added drawable->{x,y} before calling down, which is wrong since the misprite code already adds them in its check. (Alternatively, the misprite code is wrong, but there are actual users who would notice if that code was broken). (b) It didn't account for the width of the interpolation filter, so if the Picture had a bilinear or convolution filter, the edges surrounding the source area would not be validated. (c) It didn't validate alpha maps. Finally, computing the bounding box of the transform on every composite request was a real performance issue in pixman, so presumably it could be one here as well. This patch changes miSourceValidate() to simply validate all of the underlying drawable.

2011-02-26Move miTrapezoids() into fb as fbTrapezoids()Søren Sandmann Pedersen3-72/+1
The main consumer of trapezoids, cairo, is using the Trapezoids request, which is currently implemented in the miTrapezoids() function. That function splits the request into smaller bits and calls lower level functions such as AddTrap. By moving the implementation of the whole request into fb, we can instead call pixman_composite_trapezoids() to do the whole request in one step. There are no callers of miTrapezoids in any of the open source drivers, although exa and uxa have their own copies of the function.

This is a combination of a huge mechanical patch and a few small fixups required to finish the job. They were reviewed separately, but because the server does not build without both pieces, I've merged them together at this time. The mechanical changes were performed by running the included 'fix-region' script over the whole tree: $ git ls-files | grep -v '^fix-' | xargs ./fix-region And then, the white space errors in the resulting patch were fixed using the provided fix-patch-whitespace script. $ sh ./fix-patch-whitespace Thanks to Jamey Sharp for the mighty fine sed-generating sed script. The hand-done changes involve removing functions from dix/region.c that duplicate inline functions in include/regionstr.h, along with their declarations in regionstr.h, mi.h and mispans.h.
