2012-03-23cairo: Add some missing doc entries for cairo_raster_source_pattern_tChris Wilson2-1/+10
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-03-23win32: mark-dirty cannot assume the fallback has been discardedChris Wilson1-2/+1
Flushing only releases the fallback if we flush twice with no intervening damage (the theory is to try and reduce readbacks). So it is possible for a correctly behaving application to call mark-dirty and there still be a fallback. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-03-23gl: GL_UNPACK_ROW_LENGTH does not accept negative valuesIgor Oliveira1-3/+4
Use the slow fallback path if passed an image with a negative stride. Fixes negative-stride-image.
2012-03-23win32: Copy back the fallback damage to the right locationChris Wilson1-5/+6

2012-03-22gl: use direct mode for uploading gradient textureHenry Song1-32/+20
The gradient is relatively small and any differences between upload methods should be hidden by the caching. As it stands, using pbo with the gradient fails with fglrx. As the workaround to use a simple TexImage2D is inconsequential (may even be a minute win) and simplifies the code, just do it.
2012-03-22directfb: Tweak, tweak, tweak.Chris Wilson1-72/+16
A couple of mistakes, such as inverting the logic as to when to flush damage back from the shadow, meant that nothing happened when drawing to the directfb surface. Again still only compile tested. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-03-22win32: Remove obsolete font rendering routinesChris Wilson1-187/+0
These are now done by cairo-win32-gdi-compositor. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-03-22win32: Hook up glyph creation againChris Wilson1-19/+61
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-03-21win32: Fix damage flushingChris Wilson2-13/+34
The damage wasn't being created on the right surface, so the damage to the fallback image surface was not being tracked. Perform a little bit of juggling so that we track dirty regions on the fallback surface itself. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-03-20win32: Check for damage before blittingChris Wilson1-1/+1
During the surface flush, we reduce any pending damage and then blit. If no damage had been accrued then the damage->region would be NULL leading to a segfault. Patch suggested by Szuromi Gábor.

2012-03-13scaled-font: Ignore empty glyphs when checking for potential overlapHenry (Yu) Song1-0/+3
A zero-sized box contains no pixels and so cannot overlap, but it does still need to contribute to the extents.
2012-03-13subsurface: Avoid potential crash when subsurface's size is less than 0Chuanbo Weng1-0/+5
When cairo_surface_create_for_rectangle() is given non-integer parameters, the subsurface's size may be negative(e.g x = 0.2, width = 0.7, the final width will be -1). This illegal surface may cause crash somewhere upon later use, and although the fractional subsurface is ill-defined, we should never crash!
2012-03-13spans-compositor: Only destroy the clip if we made the copyChris Wilson1-2/+2
The extents->clip may be replaced elsewhere and so we cannot assume that simply because it changed from the stashed value, that it was us that made that copy. So becareful to only free our copy. Fixes a double-free of a clip after a complex fallback operation. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-03-12clip: Intialise polygon fill-rule prior to useChris Wilson1-2/+3
The earliest use of the clip path's polygon fill rule is now for intersecting the original polygon with the plurality of clip boxes. However, the initialisation of the fill rule remained after the intersection. ==8968== Conditional jump or move depends on uninitialised value(s) ==8968== at 0x4C99449: _cairo_polygon_intersect (cairo-polygon-intersect.c:1382) ==8968== by 0x4C9B788: _cairo_polygon_intersect_with_boxes.part.12 (cairo-polygon-intersect.c:1520) ==8968== by 0x4C6AE6E: _cairo_clip_get_polygon (cairo-clip-polygon.c:104) ==8968== by 0x4CAA667: clip_and_composite_boxes.part.13 (cairo-spans-compositor.c:773) ==8968== by 0x4CAAD1D: clip_and_composite_boxes (cairo-spans-compositor.c:758) ==8968== by 0x4CAB25C: _cairo_spans_compositor_fill (cairo-spans-compositor.c:1023) ==8968== by 0x4C6CB69: _cairo_compositor_fill (cairo-compositor.c:184) ==8968== by 0x4C7CE3E: _cairo_image_surface_fill (cairo-image-surface.c:945) ==8968== by 0x4CAE2B6: _cairo_surface_fill (cairo-surface.c:2047) ==8968== by 0x4C74AB7: _cairo_gstate_fill (cairo-gstate.c:1268) ==8968== by 0x4C6E6D3: _cairo_default_context_fill (cairo-default-context.c:1009) ==8968== by 0x4C67944: cairo_fill (cairo.c:2105) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2012-03-10mono-scan-converter: Use edge->is_vertical flagChris Wilson1-5/+7

2012-03-10hash: Keep a simple lut in front of the main hashChris Wilson1-6/+20
Whilst we wait for IvyBridge with its fast integer divide, in the meantime avoid the overhead by inspecting a smaller simpler cache before doing the full hash table lookup. Shaves around 10% off glyph microbenchmarks for -image. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2012-03-10doc: symbol names in header and comment must matchNis Martensen2-4/+4
The names of the function arguments in the function prototype and in the description comment must match, otherwise gtk-doc is confused.

2012-03-10doc: preserve whitespace by using docbook screen tagNis Martensen2-11/+11
Using the programlisting tag is not appropriate everywhere. Use the screen tag where the formatting shall be preserved and the text is no code listing. Also add whitespace to prevent gtk-doc from inserting paragraph breaks. Signed-off-by: Uli Schlachter <psychon@znc.in>

2012-03-08surface: Relax assertion about not rendering to a snapshotChris Wilson1-1/+3
Recently I began using the surface->snapshot_of member of a subsurface to cache a target representation of the current subsurface. More recently, I discovered this caused an assertion failure in epiphany, and probably other GTK3 based programs. Throwaway the assertion and trust that the programmer doesn't make any mistakes...

2012-03-07gl/msaa: Do not attach a depth-stencil attachment to the default framebufferMartin Robinson1-0/+3
Only texture surfaces need to have a depth-stencil attachment. The default framebuffer is responsible for managing its own depth and stencil attachments.
2012-03-06xlib: Apply the glyph offsetChris Wilson1-5/+5
The (dst_x, dst_y) parameters passed to the XRenderCompositeText are misleading and do not perform any adjustment, so we have to do it ourselves. Fixes clip-operator Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
