for supporting & storing spesific OS data of the surfaces
for example on Windows platform it is needed to save for each windowSurface
the HWNDL & HDC of the native window, this change caused changes in the EglOsApi
interface
On windows it is not possible to create a context which
shares with another context if the other context is already
current to some thread.
This change makes the "global context" be a dummy context
on windows which we create during the first createContext
call, this dummy context will never bind to any thread so
it is safe to share with it at any time.
On windows we need to have a thread on the renderer process
which handles windows messages sent to the subwindow
we are creating during framebuffer initialization.
We run this message pump in the main renderer thread
and the server listener on a seperate thread.
The following enables the renderer build on darwin.
Moved platform specific type declarations from render_api.h
to render_api_platform_types.h so it can be included from the
objective c code.
Fixed subwindow to use EmuGLView which overrides NSView to prevent
background drawing of the view.
Mac specific bug fix to support unbinding a context.
Removed NSOpenGLContext:clearDrawable call before binding
an NSView to the context to avoid re-paint of the view which
causes flash effect.
the dispatch loaded incorrect functions from GL for framebuffer extension
the functions used belong to GL3, and didn't work with GL2 context
fixed this to use the EXT functions from GL
The shaders fail to compile if we don't omit those changes (Cordy game for example).
Anyways, they have no semantic meaning in GLSL, quote for GLSL 4.1 spec:
"Precision qualifiers are added for code portability with OpenGL ES, not for functionality. They have the
same syntax as in OpenGL ES, as described below, but they have no semantic meaning, which includes no
effect on the precision used to store or operate on variables."
Also removed an anoying print in the encoder.
those are up-to-date gles header files from khronos so that
host applications will be able to compile with the translator
with no dependencies. The translator now exports both egl/gles
headers and their implementation libraries.
There are Android applications (notably BootAnimation) which require
exactly an RGB_565 configuration, and are not satisfied by an e.g.
RGBA_8888 configuration. This doens't make too much sense, and I think
such apps should be fixed.
However, until that happens, there is an issue when the host does not
have an RGB_565 FBConfig, which is typical to many OpenGL implementations.
In such cases, BootAnimation doesn't run.
The workaround is to add an RGB_565 config to the list maintained by the
translator, which is basically an 888 config in disguise.
This commit add CHECK_GL_ERROR define to decoders/renderer which enables various
glGetError() calls. Also changed emugen to add glGetError() after every dispatch call (based on
defintion of CHECK_GL_ERROR). Also cleaned some annoying printf's.
When sorting configs, we want the conformant ones first.
This also makes Wave Blazer Lite work - specifically by placing a non
conformant config (rgba=0) at the end of the list.
The application provides the window handle to which the
OpenglRenderer should render to however only a sub-region of
this window needs to be rendered. This change adds this functionality
by creating a native child subwindow into which rendering will happen.
When translating point size arrays from GLES to GL, an optimization
was implemented where all points of the same size in an array or elements
array where drawn together. This is wrong, since it means points
are not drawn in the order the app has requested, creating the wrong
result when points in the array are overlapping in screen space.
So removed this mechanism, and now just drawing the points in the right
order.
Some optimization is still there, where if there are several
consecutive points of the same size they are drawn together.
The change in GLEScmImp.cpp is only to make the condition more readable -
the functionality is identical.
