* Give DrawState a real copy constructor, handle deriving in PushState().
(Although clipping region and alpha mask are not cloned, which is on the
other hand just what's needed for now.)
* Combining alpha masks from previous states is not yet handled.
* Remove SetAlphaMask() from DrawingEngine and Painter. It is now done in
SetDrawState().
... both vector and bitmap based. Sub-pixel text rendering not yet handled,
I think the scanline is used differently in this case, in that three times the
horizontal resolution is used, while the alpha map doesn't match this
increase.
* agg_clipped_alpha_mask is a modified version of agg alpha mask class,
allowing us to offset the mask bitmap to follow the view position, and
also allows "inverse" clipping, where everything outside the bitmap is
considered inside the clipping region.
* AlphaMask is a container class keeping the ServerPicture, it's bitmap
rendering, and other relevant information. It will be used to save and
restore the clipping picture as part of the view state.
* Because these classes introduce more coupling within app_server, it's
not possible anymore to split out tst_app_server from
libtestappserver.so. Instead, move everything to libtestappserver.so,
except the things that actually need to not be there (to avoid
interferences with the host API). As a result, the previously introduced
stub cpp file to work around this problem isn't needed anymore.
The design for all this (and the previous commit) is Stippi's work.
Thanks for the advice and implementation hints!
Use AGG to implement ClipToPicture in a faster and better way.
There are things missing in this initial implementation:
* No support for PushState/PopState saving and restoring the picture.
* No support for nested clipping through PushState
* The clipping doesn't happen where you expect it when using SetScale()
* There are artifacts when scrolling and resizing clipped views
* The implementation uses more memory than it needs, as the clipping
bitmap is stored as RGBA32, yet only the alpha channel is used
* The clipping bitmap is rendered more times than it needs to. We need
some caching here.
* Also some WIP towards integrating TextListener.
* Everything untested.
* Fixed a bug where copying to the clipboard had an extra line-break
after each paragraph since the recent changes that made sure each
paragraph ends in a line-break.
Update the style of this preference app to match Haiku’s coding guidelines.
Since this app used a completely different style this is a big commit, but,
there should be no behavioral changes.
Style changes include but are not limited to:
* private member variables use fMemberVariable style
* local variables and public member variables use camelCase style
* compare pointers to NULL explicitly
* compare integers against 0 explicitly
* always flank binary operators with spaces such as + - , / *
* pointer goes with type, not value or flanked by spaces
* lots of variable renaming especially for abbreviations
* comments start with a leading space, prefer lowercase unless full sentence
* space after keywords such as if and for and { and } on same line
* multi-line if statement style fixes
* remove trailing spaces
* 80 char fixes
* ... and many more, and I'm sure I missed some.
Add/update copyright headers giving credit where due, obviously this code
can’t be copyright Haiku, Inc. from 1999 since Haiku, Inc. didn’t exist
so this change attributes copyright to Jeremy Friesner from 1999-2009 and
Haiku, Inc. from 2009 onwards matching the long description of the rdef file.
Added myself to the authors section of the files in the clv directory.
* Search for vector icons from MIME database once at start,
limit to application super-type, this fulfills a TODO in the code
* Use a std::map keyed by a hash to avoid duplicate icons
eliminating _HasBitmap()
* Store the vector representation and then only build bitmaps
when needed
* Convert uses of int to int32
* Convert from using BList to BObjectList, simplified cleanup
* Rename variables and methods to not abbreviate/be more clear
e.g. fPosX, fPosY => fPositionX, fPositionY
e.g. _GenerateCardPos() => _GenerateCardPositions()
* Renamed PairsTopButton to PairsButton
* Integrate Size submenu into New menu item.
Size menu item goes away, you can select New to get a new game at
the current difficulty, or, you can drill down in the New menu to
choose from Beginner, Intermediate, or Expert.
* Add new Size menu to set the icon size: Small (32x32), Medium (64x64),
or Large (128x128). Default is medium
* Rename MENU_SIZE message constant to MENU_DIFFICULTY for clarity
* Eliminate PairsGlobal.h, distribute constants to appropriate files.
Instead of 1/10000 we now add 1/128 to the width to compensate for
rounding inaccuracies. Due to the limited float mantissa precision
(23 bit) the previous value would already have no effect for relatively
small widths (>= 128).
Fixes#10455.
For non-US keyboards, the extra 102th/105th key is used to reach \. But,
we also need it to report | when shifted (this is the key left to
"enter").
This affects only USB keyboards. Thanks to gordoncjp for reporting!
User timers may cause another thread to become ready in which case we would
like this to happen before scheduler_reschedule() chooses next thread to
be executed.
