Since those GraphcisManager initialize the cursor position to (0,0) when
created the cursor was jumping to the top left corner and then moving
back to its initial position as soon as the mouse was moved. Now it
stays at its initial position.
There are still some issues with it when changing between OpenGL and
SurfaceSDL at the same time as toggling fullscreen. But it is not worse
than before.
If we do not update the area below the message, it is just blitted on top
of itself again and again and gets progressively less transparent. It also
causes artefacts when the mouse pass below the OSD message.
On the OpenPandora handheld, the OSD message would not render unless you
moved the cursor in the area where it was supposed to show.
Additionally, the OSD message was not transparent like in v1.8.
This commit fixes both these issues.
When a user tries to add a game expecting it to be a particular
game for a particular engine, but a detector from another engine
happens to match some files that exist in the game directory and
reports on those files instead, this can cause a lot of confusion
because the detector doesn't say what engine or game it thought it
matched.
This patch adds the name of the matching engine as well as any
matching game IDs (if applicable) to the detector's logged output.
It also provides more specific guidance about where to send the
detection information (to the bug tracker), and properly wraps the
first part of the report to 80 columns.
Refs Trac#10272.
If an early file in the game's signature list has a hash/size
mismatch, it is still necessary to continue to check the rest of
the candidate files for existence, since the non-existence of
candidate files is supposed to disqualify a game description as
matching a game to an unknown variant.
By quitting the file check early, the detector had been allowing
descriptions to randomly match if there happened to be an early
file in the detection list with the right name but wrong hash/size,
even if some of the other signature files did not exist at all.
Previous patches that removed shifts of constant negative values
to eliminate UB were valid, but did not correct all places where
this engine was potentially bit shifting negative values. There is
no reason to not just use multiplication and division and let the
compiler make the right choice for optimisation for an
architecture, so that is what this patch does.
This improves the output of static assertions in all compilers,
and prevents problems in MSVC 2015 where the mechanism for
triggering a compilation error in C++98 mode may cause errors when
that compiler builds in release mode.
Fixes Trac#10154.
Fixes out of bounds reads in the Myst ME intro videos.
OOB reads may happen because:
- The bitstream implementation reads 4 bytes at a time, and the buffer
size is not guaranteed to be a multiple of 4.
- The huffman parsing code reads a fixed amount of bits when it
sometimes needs not all of them.
Also fixed bits vs bytes mismatch for the size parameter of the calls to
the bitstream constructor, and removed a few unnecessary heap
allocations.
Fixes#10220.
While usage of these pointers was technically safe because they
were read through an alignment-aware API, taking the address of an
unaligned pointer was generating warnings in Clang, and is not
strictly necessary here. This change solves the warning and also
protects this code from any future change that might cause it to
start reading unsafely.
Warnings are as follows:
"In the GNU C Library, "minor" is defined by <sys/sysmacros.h>.
For historical compatibility, it is currently defined by
<sys/types.h> as well, but we plan toremove this soon.
To use "minor", include <sys/sysmacros.h> directly. If you did
not intend to use a system-defined macro "minor", you should
undefine it after including <sys/types.h>"
