- Do not enable any multisampling as for FBOs it is not
supported anyhow.
- Just restore GL_BLEND and GL_STENCIL_TEST manually
=> Getting rid of the huge load of glPushAttrib/glPopAttrib
gets us a huge performance boost, especially for drivers
with slow state stack implementations.
- Prevent writing to property tree in wrong thread.
- Add Element::getBoundingBox and
Element::getTightBoundingBox as uniform way to
retrieve bounding boxes of all canvas elements.
- Update path bounding boxe in update traversal.
Returning somehow valid data in case it is used unchecked was
probably not a good idea. Better fix the code using it^^
This fixes#1421.
This reverts commit 3525fff8d0.
Return an invalid bounding box can lead to problems
if used unchecked. Just returning an empty bounding
box (size 0x0 and position at the origin of the
element) is much safer.
- Calculate local/client position for every drag event
instead of just reporting the position of the initial
mousedown event.
- Only pressing the same button multiple times increases
the mouse clickcount.
- Update clipping rect if canvas view or texture size
changes.
- Add new property "clip-frame" to specify coordinate
frame for "clip" coordinates. Coordinates can be
global, relative to the parent or relative to the
element itself.
If setting properties on a group a check is performed if
this property exists on any possible child element, and
only if this is the case the property is stored in the
groups style.
Previously elements have been only initialized during
their first usage, leading to ignored styles if they
have been set on a parent element before instantiating
an instance of the actual element type.
Removing text elements failed due to prefering removing the
style property with the same name. Add a flag to each style
indicating whether it can be inherited. The text property
is only applicable to text elements and can not be inherited.
Now groups can not have a text property, avoiding the name
clash with the text element.
