Add initial support for NV_path_rendering extension to gpu command buffer
Add initial support for NV_path_rendering extension to gpu command
buffer. This is needed in order to support NV_path_rendering
implementation in Skia.
Implement this by creating a new GL ES pseudo-extension called
CHROMIUM_path_rendering. The CHROMIUM_path_rendering extension
will be exposed to clients only if the context is not a webgl context,
NV_path_rendering extension is present. Also, EXT_direct_state_access
extension must be present for Open GL.
Add matrix functions needed to support the feature:
void glMatrixLoadfEXT(GLenum matrixMode, const GLfloat* m)
void glMatrixLoadIdentityEXT(GLenum matrixMode)
NV_path_rendering needs these functions to implement transformations
for the path drawing.
Changes the build_gles2_cmd_buffer.py to be able to generate context
state variables that are arrays. The state variable is defined to be an
an array when its default value is an array.
Changes the build_gles2_cmd_buffer.py to round the float GL state
variables with round() when querying them with GetInteger.
The values GL_*_CHROMIUM tokens added match the values of corresponding
GL_*_NV tokens from the NV_path_rendering extensions. This is why the
values are passed after validation to the receiving GL function, without
any mapping.
