2011-02-26Move miTriangles to fb as fbTriangles()Søren Sandmann Pedersen4-126/+1
The fb version simply calls the new pixman_composite_triangles(). This allows us to get rid of miCreateAlphaPicture(). Reviewed-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Søren Sandmann <ssp@redhat.com>
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.

2010-12-31render: Enable animated cursor block handler only when neededPauli Nieminen1-5/+13
Calling BlockHandlers takes some time for each iteration in main loop which adds up quickly over multiple request. To reduce the round-trip costs to xserver BlockHandlers should be registered only when required. AnimCurScreenBlockHandler is the first victim for this optimization.

2010-06-05Rename region macros to eliminate screen argumentKeith Packard3-32/+32
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.

2010-06-03Move each screen's x/y origin into ScreenRec.Jamey Sharp1-22/+22
Many references to the dixScreenOrigins array already had the corresponding screen pointer handy, which meant they usually looked like "dixScreenOrigins[pScreen->myNum]". Adding a field to ScreenRec instead of keeping this information in a parallel array simplifies those expressions, and eliminates a MAXSCREENS-sized array.

2009-10-01render: Fix crash in RenderAddGlyphs (#23645)Peter Hutterer1-1/+5
This patch fixes two bugs: size is calculated as glyph height * padded_width. If the client submits garbage, this may get above INT_MAX, resulting in a negative size if size is unsigned. The sanity checks don't trigger for negative sizes and the server goes and writes into random memory locations. If the client submits glyphs with a width or height 0, the destination pixmap is NULL, causing a null-pointer dereference. Since there's nothing to composite if the width/height is 0, we might as well skip the whole thing anyway. Tested with Xvfb, Xephyr and Xorg.
