2753b4243e glmemory: add wrapped data pointers to setup_buffer
Allows creating wrapped memories with GstGLAllocationParams.

The wrapped pointers will be set in the parameters before being passed
to the memory allocation function.

which is required for some memory implementations.

0c2890cd34 glmemory: add checking the read implementation format/type on gles2 platforms
By default, reading GL_RED or GL_RG us unsupported by glReadPixels unless
exposed through GL_COLOR_READ_IMPLEMENTATION_FORMAT/TYPE.  This allows
downloading multiple-planar video frames where possible.

b1bfcac299 glmemory: unset GL_UNPACK_ROW_LENGTH in opengl3
If the user uploads their own texture without setting the unpack length, then
then the result will have the appearance of stride mismanagement due to
an incorrect row length.

28dbe4fffc glmemory: add gst_gl_memory_allocator_get_default
Add gst_gl_memory_allocator_get_default to get the default allocator based on
the opengl version. Allows us to stop hardcoding the PBO allocator which isn't
supported on gles2.

Fixes GL upload on iOS9 among other things.

  needed.

76a38dd66a glmemory: base classify and add the pbo memory on top
The base class is useful for having multiple backing memory types other
than the default.  e.g. IOSurface, EGLImage, dmabuf?

The PBO transfer logic is now inside GstGLMemoryPBO which uses GstGLBuffer
to manage the PBO memory.

This also moves the format utility functions into their own file.

fa1c4e552c glmemory: take subsampling into account for rectangle textures
Rectangle textures don't use normalized coordinates so subsampling needs to be
factored in explicitly.

18f9dfdfe5 glbufferpool: add bufferpool options for the various texture targets
This was chosen over relying solely on the caps as glupload needs to propose an
allocation and set the texture target based on the output caps.  Setting the
caps in the config is currently pointless as they are overwritten in a lot of
element's decide_allocation functions.

This provides a mechanism for the buffer pool to be configured for a certain
texture target when none has been configured.

functions.

Update the relevant caps/templates for 2D only textures.

fce0e0ba3c gl: add and use gst_gl_internal_format_rgba
Previously when compiling GstGL with both GL and GLES2,
GL_RGBA8 was picked from GL/gl.h. But a clash may happen at
runtime when one is selecting GLES2.

gst_gl_internal_format_rgba allows to check at runtime
if it should use GL_RGBA or GL_RGBA8.

cc587ce1f1 glmemory: properly detect (hopefully) the correct ext_rg/arb_rg variant
GL_EXT_texture_rg is only valid for GLES2. GLES3 uses similar wording to
the GL_ARB_texture_rg which requires a sized internal format that the
GL_EXT_texture_rg does not require.

af023d7c95 glememory: only store and act on the map flags on first/last map/unmap

is accessing our data pointer or texture resulting in mismatched video
frames.

966cad27d7 gl: initial support for texture targets other than GL_TEXTURE_2D
Make GstGLMemory hold the texture target (tex_target) the texture it represents
(tex_id) is bound to. Modify gst_gl_memory_wrapped_texture and
gst_gl_download_perform_with_data to take the texture target as an argument.

This change is needed to support wrapping textures created outside libgstgl,
which might be bound to a target other than GL_TEXTURE_2D. For example on OSX
textures coming from VideoToolbox have target GL_TEXTURE_RECTANGLE.

With this change we still keep (and sometimes imply) GL_TEXTURE_2D as the
target of textures created with libgstgl.
