* Support empty inline elements in block tags in QTextDocumentEskil Abrahamsen Blomfeldt2014-02-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the following case: <blockquote> <span />Foobar </blockquote> Qt would see the end of <span>, and consider the current block tag as closed, thus resetting the block format, thus losing the margin set for the current block (due to blockquote). If you do <blockquote> <span>Foo</span>Foobar </blockquote> instead, then the same would not happen, since hasBlock is set to false when we append text to the current inline node. [ChangeLog][QTextDocument] Add support for empty inline elements in block tags.

| | | | | | | | | | HarfBuzz-NG does character mirroring where appropriate. A simple solution is to unset RightToLeft shaper flag when text gets shaped with HB-NG.

* QOpenGLTextureHelper: fix the DSA emulationGiuseppe D'Angelo2014-02-032-217/+241
| | | | | | | | | | | | | | | | | | | | | | The DSA emulator functions query which texture is currently bound to a given target, then bind the new one, perform an operation, and bind the old one back. The problem is that in order to query what's currently bound to the GL_TEXTURE_<X> target one needs to call glGetIntegerv passing GL_BINDING_TEXTURE_<X>. Since both GL_TEXTURE_X and GL_BINDING_TEXTURE_X values are completely arbitrary (not contiguous nor related in any way) we need to pass *both* them to the functions. The right GL_BINDING_TEXTURE_X was getting already chosen (and stored) at texture creation time by QOpenGLTexture, so it's just a matter of passing it around. For the "real" DSA functions, the binding target is ignored.

* Optimize drawing to and from generic formatsAllan Sandfeld Jensen2014-01-311-102/+359
| | | | | | | | | | | | | | | | | When drawing to and from the less common formats most of the cpu time is spend in conversion. The conversion method is rather slow due to using variable shifts and masks that the compiler does not have a chance to optimize. This patch changes the conversion methods to being templates fed by constexpr methods. This allows the compiler to fully optimize the methods yielding 2x->5x speedups. The reliance on constexpr however means the optimized methods are only used under C++11.

| | | | | | | | | | | | | | | | | | | | | | | | | | Now the only way to enable Neon support is to change the mkspec. [ChangeLog][Important Behavior Changes] Qt no longer checks for support for the Neon FPU on ARM platforms at runtime. Code optimized for Neon must be enabled unconditionally at compile time by ensuring the compiler supports Neon. You may need to edit your mkspec for that.

* | Remove runtime detection of SSE2Thiago Macieira2014-01-166-85/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the compiler supports SSE2, we'll use our SSE2-optimised code unconditionally. Runtime detection is left for SSSE3 code. The SSE2 codebase is big and thus a timebomb if an inline function gets leaked out and run without runtime check. In reality, it's extremely unlikely people running CPUs without SSE2 support are running Qt 5 at this moment (they're either too old or too new, e.g. Intel Quark). The SSSE3 codebase is a lot more manageable.

As a part of these additions, one Phags-pa character has the Joining_Type value of L (Left Joining), which no character had been assigned before. * The unassigned code points in the Currency Symbols block have been given the Bidi_Class property value ET and the Line_Break property value PR, to help implementations support new currency symbols, when they are encoded. * Hebrew letters and basic punctuation marks have been assigned the newly introduced Word_Break property values Hebrew_Letter, Single_Quote, and Double_Quote. * The Bidi_Class property has been extended with four new values for directional isolates.
