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.
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.
This fixes three issues:
1. glGet(GL_2d_TEXTURE_BINDING) should be handled by the translator rather
than by OpenGL.
2. glIsTexture shoud return GL_TRUE only if the texture was bound at some
point - add a wasBound member to the TextureData and maintain it.
3. glTexParameter(GL_GENERATE_MIPMAP) did not work. The first problem was
that it was not allowed by our validator - fixed. The next issue is that
this enum is not necessarily supported by the OpenGL implementation - it
is in OpenGL 2.x, but was replaced by an extension in 3.x. So in case the
extension does not exist, and GL_GENERATE_MIPMAP is required, save this info
in a new requiresAutoMipmap member of TextureData and call glGenerateMipmapExt
whenever glTex(Sub)Image2D is called.
There is a theoretical case where neither GL_GENERATE_MIPMAP nor glGenerateMipmap
is supported by the OpenGL implementation - this is not likely to happen, but
if we find such an implementation it might require implementing a mipmap
generation software algorithm (which is bad).
There is a set of glGets which query the client state of the
binded arrays. The data exists in the translator context and is not
passed to GL, so the glGets should be handled internaly.
This is done by implementing four glGet*v methods in GLEScontext, which
return a boolean value indicating whether we have set the return value
or not, and are called by the glGet*v functions in GLEScmImp.
Two of the glGets are handled by GLEScontext, and the other 15 by
GLEScmContext since they are specific to GLES 1.1. The same should be
done for 2.0 specific glGets in a later patch.
Also. bufferName is now saved in GLESPointer in to allow the
GL_*_ARRAY_BUFFER_BINDING get.
Our implementation of eglGetProcAddress() resolves the function addresses
in run time. Typically this is not an issue, but when a gl function is
also implemented by the calling app the address was resolved to the calling
app's version of the function rather than ours. This is the case with the
glDrawTex{isfx}OES functions in the 1.1 conformance test.
The solution is to add the -Bsymbolic switch when linking our libraries,
so all symbol resolution is done internaly.
The same fix should probably be done for Mac.
inserting some of the logic which was scattered over some parts
of the GLESContext class to be encpsulated inside the ConversionArrays
so that the code will be more clea and organized.

fix object name manager to accept objects with name 0
fix unbinding of buffers,framebuffers and renderbuffers
separate getPointer to have specific implementation for gles 1 and 2
fix number of supported texture images to match GL
fix incorrect optimization that skips draw on false conditions
fixed functions calling conventions in dispatch tables,
added link flag to translator libraries to produce an alias

This patch is a major rework of the build opengl-emulation
build scripts. See README for details.
In a nutshell, this introduces various functions that considerably
simplify the declaration of the 26+ modules in this implementation,
by handling auto-generation of sources and module imports/exports.

When re-binding the same context the resoult was that the
surfaces got unbinded from the context.
Fixed that situation and added an optimization to do nothing
in case of re-binding the same context to the same binded surfaces.

This change turns GLcommon to be static instead of shared
library.
Removed the s_globalNameSpace static object from objectNameManager
and moved it to live inside the EglDisplay object which is shared
for all display space objects (GLESv1, GLESv2 and EGL).

Some native types like NativeFBConfig and NativeContext are
internal to the translator implementation and should not
exist in the interface headers.
Moved those types from eglplatform.h into eglinternalplatfom.h

Initialize the GLDispatch with dummy function instead of

such function is made.
