- 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.
Get rid of the possibilty to keep delted children. This was not
used actively, required unnecessary memory for each property node
and lead to subtile bugs, as creating a node after a node with
the same path has been deleted resulted in getting the old node
back instead of a cleanly initialized one.
Store unhandled xml attributes in a subnode named _attr_ for each
node on parsing propertylist files. This allows retrieving them at
a later stage where there is no access to the source xml file any
more.
Writing to a closed socket on all Unix/Linux systems raises
a SIGPIPE signal which immediately closes the program. Disabling
raising of SIGPIPE allows proper error handling by checking the
return values of send/sendto and getting the EPIPE in errno.
Using a static naGhostType ensures that always the same
address is used for the same ghost and prevents ghost_types
from getting invalid (eg. on reset).
Slave objects can now rotate around two axis to always track the
target - even when it is outside the plane perpendicular to the
lock-axis of the root object. This allows for example animating
levers with non-parallel axis of rotation connected with a rod.
- 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.
- refactor code used multiple times spread over sg/fg into
one single location.
- allow aborting requests.
- Provide two common request types:
* FileRequest: Save response into file
* MemoryRequest: Keep resonse in memory (std::string)
- extend HTTP::Client interface:
* urlretrieve: Save url to file (shortcut for making a
FileRequest)
* urlload: Get respons into memory (shortcut for making
a MemoryRequest)
New functions naCallMethodCtx and naCallMethod to replace
NasalSystem::callMethod from FlightGear. This has just added an
unneeded level of indirection and fits better directly into Nasal.
naSetErrorHandler can be used to register an error handler/logging
function.
These new functions are meant to replace the gcSave/gcRelease
methods of the NasalSystem class in FlightGear, as passing an
adapter to SimGear from FlightGear is quite a lot of useless work
just for being able to save objects.
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.
